I2C / UART level shifter

Edit

1.8 V sensor, 3.3 V MCU. An auto-bidirectional translator, not a pile of MOSFET tricks you will forget to bias.

Starting part numbers

From the local map. These are examples, not the live result list.

  • PCA9306DCTR

    NXP

    I2C-specific, the safe choice for a bus.

  • TXB0108PWR

    Texas Instruments

    8-bit auto-bidirectional; watch capacitive load.

Live parts

On-demand from Nexar and/or DigiKey. Nothing here is a catalog Byuse owns. Specs appear only if the API returned them.

No distributor key is set. Browsing still works. To see live parts, add one of these pairs to .env.local and restart the dev server:

  • NEXAR_CLIENT_ID
  • NEXAR_CLIENT_SECRET
  • DIGIKEY_CLIENT_ID
  • DIGIKEY_CLIENT_SECRET

Nexar needs NEXAR_CLIENT_ID and NEXAR_CLIENT_SECRET. DigiKey needs DIGIKEY_CLIENT_ID and DIGIKEY_CLIENT_SECRET.
