For that reason, we like using 4050\/74LVX245 series and similar logic to perform proper level shifting. Only problem is that they are only good in one direction which can be a problem for some specialty bi-directional interfaces and also makes wiring a little hairy.\u003cbr\u003e\u003cbr\u003eThat's where this lovely chip, the TXB0108 bi-directional level converter comes in! This chip perform bidirectional level shifting from pretty much any voltage to any voltage and willauto-detect the direction. Only thing that doesn't work well with this chip is i2c (because it uses strong pullups which confuse auto-direction sensor). If you need to use pullups, you can but they should be at least 50K ohm - the ones internal to AVRs\/Arduino are about 100K ohm so those are OK!

Furthermore, it doesn't introduce slew compared to traditional voltage dividers. This item is perfect for special bi-directional interfaces that talk to the microcontrollers in both ways. Note that since the item is bi-directional, it does not have a strong output that can drive LEDs or long cables. If you don't need the bi-direction feature, we suggest using the 74LVX245 instead.\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eSpecifications:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul style=\"margin-top: 10px; margin-bottom: 10px; padding-left: 15px; list-style-position: inside;\"\u003e\n\u003cli style=\"list-style-type: disc;\"\u003eDimensions: 18mm x 13mm x 2mm \/ .7\" x .5\" x .08\"\u003c\/li\u003e\n\u003cli style=\"list-style-type: disc;\"\u003e1.2 V to 3.6 V on A Port and 1.65 V to 5.5 V on B Port (VCCA ≤ VCCB) \u003c\/li\u003e\n\u003cli style=\"list-style-type: disc;\"\u003eLow Power Consumption, 5-μA Max ICC\u003c\/li\u003e\n\u003cli style=\"list-style-type: disc;\"\u003eESD Protection Exceeds JESD 22 \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eLibrary: \u003c\/span\u003eNone\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eInclusions: \u003c\/span\u003e1 x Bi-Directional Level Shifter TXB0104\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eDocuments:\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul style=\"margin-top: 10px; margin-bottom: 10px; padding-left: 15px; list-style-position: inside;\"\u003e\n\u003cli style=\"list-style-type: disc;\"\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/datasheets\/txb0104.pdf\" style=\"\"\u003eTXB0104 Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli style=\"list-style-type: disc;\"\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/datasheets\/txb0108appnote.pdf\" style=\"\"\u003eTXB010X App note detailing how it works!\u003c\/a\u003e\u003c\/li\u003e\n\u003cli style=\"list-style-type: disc;\"\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Fritzing-Library\" target=\"\" style=\"\"\u003eFritzing object in Adafruit Fritzing library\u003c\/a\u003e\u003c\/li\u003e\n\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit-TXB0104-Level-Shifter-Breakout-PCB\" target=\"\" style=\"\"\u003e\u003c\/a\u003e\u003cli style=\"list-style-type: disc;\"\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit-TXB0104-Level-Shifter-Breakout-PCB\" target=\"\" style=\"\"\u003eEagleCAD PCB files on GitHub\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003cstyle\u003e\n.product-copy{line-height:1.7}\n.product-copy \u003e * + *{margin-top:1rem}\n.product-copy h2{margin:1.4em 0 .6em}\n.product-copy p{margin:0 0 1em}\n.product-copy ul,.product-copy ol{margin:0 0 1.2em 1.2em}\n.product-copy li{margin:.35em 0}\n.product-copy table{width:100%;border-collapse:collapse;margin:1.2em 0}\n.product-copy table th,\n.product-copy table td{border:1px solid #eee;padding:.6em .75em;text-align:left}\n.faq-list{margin:1.2rem 0 1.4rem}\n.faq{border:1px solid #e6e6e6;border-radius:12px;padding:.75rem 1rem;margin:.6rem 0;background:#fafafa}\n.faq summary{font-weight:600;cursor:pointer}\n@media (min-width:768px){ .product-copy{font-size:1.02rem} }\n\u003c\/style\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":45813863186721,"sku":"2464","price":159.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/1491\/5617\/products\/bi-directional-level-shifter-txb0104-1125.jpg?v=1689672961"},{"product_id":"quad-level-shifter-3v-to-5v-74ahct125","title":"Adafruit Quad Level-Shifter 3V-5V 74AHCT125 - 1787","description":"\u003cdiv class=\"product-copy\"\u003e\n\n\u003cp\u003eLevel shifting chips let you connect 3V and 5V devices together safely.

That's right, now you can shrink your Arduino projects down to \"tiny size\" by moving your code straight over to these small but capable ICs. The standard method for programming the ATtiny ICs involves a breadboard, lots of jumper wires, and a hardware programmer, but David Mellis over at MIT Media Lab has simplified the process by laying out this handy USB programmer.\u003c\/p\u003e\n\u003cp\u003eThe Tiny AVR Programmer plugs directly into your USB port and provides a programming socket for the ATTiny45 and 85. Just slot an ATtiny with a DIP footprint into the socket, plug the programmer into your USB port and start up the Arduino IDE. After installing the proper board definitions, you simply program it the same way you would any other Arduino board. The programmer even breaks out the IC pins to female headers so you can easily prototype around the ATtiny without pulling and plugging it over and over. There are two ISP headers that have also been broken out so you can use the programmer or solder in a 6-pin header for other AVR microcontrollers!\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cstyle\u003e\n.product-copy{line-height:1.7}\n.product-copy \u003e * + *{margin-top:1rem}\n.product-copy h2{margin:1.4em 0 .6em}\n.product-copy p{margin:0 0 1em}\n.product-copy ul,.product-copy ol{margin:0 0 1.2em 1.2em}\n.product-copy li{margin:.35em 0}\n.product-copy table{width:100%;border-collapse:collapse;margin:1.2em 0}\n.product-copy table th,\n.product-copy table td{border:1px solid #eee;padding:.6em .75em;text-align:left}\n.faq-list{margin:1.2rem 0 1.4rem}\n.faq{border:1px solid #e6e6e6;border-radius:12px;padding:.75rem 1rem;margin:.6rem 0;background:#fafafa}\n.faq summary{font-weight:600;cursor:pointer}\n@media (min-width:768px){ .product-copy{font-size:1.02rem} }\n\u003c\/style\u003e","brand":"Circuitrocks","offers":[{"title":"Default Title","offer_id":45838328267041,"sku":"2129","price":49.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/1491\/5617\/files\/attiny13a-attiny25-attiny45-attiny85-development-programming-board-avr-white.jpg?v=1778911451"},{"product_id":"sn7432n-quad-2-input-gate-dip14-discrete-devices","title":"IC SN7432N Quad 2-Input OR Gate DIP14","description":"\u003cdiv class=\"product-copy\"\u003e\n\n\u003cul\u003e\n\u003cli\u003eType\/MPN: SN7432N\u003c\/li\u003e\n\u003cli\u003eHousing\/Case: DIP14\u003c\/li\u003e\n\u003cli\u003eDate Code: 93\u003c\/li\u003e\n\u003cli\u003eDescription: 4x2 NOR *Quad 2-Input OR Gate\u003c\/li\u003e\n\u003cli\u003eRoHS: No\/Pb\u003c\/li\u003e\n\u003cli\u003eWeight: 0.04 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\n\u003cstyle\u003e\n.product-copy{line-height:1.7}\n.product-copy \u003e * + *{margin-top:1rem}\n.product-copy h2{margin:1.4em 0 .6em}\n.product-copy p{margin:0 0 1em}\n.product-copy ul,.product-copy ol{margin:0 0 1.2em 1.2em}\n.product-copy li{margin:.35em 0}\n.product-copy table{width:100%;border-collapse:collapse;margin:1.2em 0}\n.product-copy table th,\n.product-copy table td{border:1px solid #eee;padding:.6em .75em;text-align:left}\n.faq-list{margin:1.2rem 0 1.4rem}\n.faq{border:1px solid #e6e6e6;border-radius:12px;padding:.75rem 1rem;margin:.6rem 0;background:#fafafa}\n.faq summary{font-weight:600;cursor:pointer}\n@media (min-width:768px){ .product-copy{font-size:1.02rem} }\n\u003c\/style\u003e","brand":"Texas Instruments","offers":[{"title":"Default Title","offer_id":45838634451233,"sku":"2248","price":19.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/1491\/5617\/files\/sn7432n-quad-2-input-gate-dip14-discrete-devices-hires.jpg?v=1778921203"},{"product_id":"ic-74hc04n-hex-inverter-not-gate-ic","title":"IC 74HC04N Hex Inverter NOT Gate","description":"\u003cdiv class=\"product-copy\"\u003e\n\n\u003cp\u003eSix separate inverters with typical push-pull outputs are provided by the 74HC04.
