Translators

I2CLevel ShifterBuffer

The TCA9801 is a dual-channel bidirectional I2C buffer/repeater designed for level shifting between 0.8V and 3.6V, featuring an integrated current source on the B-side.

Best for

  • I2C level shifting
  • Low-power applications

Avoid if

  • B-side requires external pull-up resistors
  • Static-voltage offset buffer outputs are present on the B-side

Check before use

  • B-side load capacitance
  • Current source compatibility
