Specialized

I2C switchSMBus4-channelVQFN-16voltage translationactive-low reset

PCA9546ARGVR is a 4-channel bidirectional I2C/SMBus switch for isolating address-conflicting downstream devices or partitioning bus capacitance.

Best for

  • Separating I2C slaves with duplicate addresses
  • Four-channel I2C bus segmentation
  • Mixed-voltage I2C bus designs using external pull-ups

Avoid if

  • An I2C bus speed above 400 kHz is required
  • A single always-connected downstream bus is sufficient

Check before use

  • A0, A1, and A2 must be tied to VCC or GND
  • RESET must not exceed VCC
  • Enabled channels add to upstream bus capacitance
