Translators

I2C BufferLevel ShifterBidirectional

The TCA9803 is a dual-channel bidirectional I2C buffer/repeater with an integrated B-side current source, ideal for level-shifting between 0.8V and 3.6V domains.

Best for

  • I2C level shifting
  • Low-power bus buffering

Avoid if

  • B-side requires external pull-ups
  • B-side connects to static-voltage offset buffers

Check before use

  • B-side capacitive load
  • Supply voltage ranges
