PI4MSD5V9543A - 2 Channel I2C bus switch

General Description

The PI4MSD5V9543A is a bidirectional translating switch, controlled by the I2C bus.

The SCL/SDA channels.

Key Features

  • 1-of-2 bidirectional translating multiplexer.
  • I2C-bus interface logic.
  • Operating power supply voltage:1.65 V to 5.5 V.
  • Allows voltage level translation between 1.2V, 1.8V,2.5 V, 3.3 V and 5 V buses.
  • Low standby current.
  • Low Ron switches.
  • Channel selection via I2C bus.
  • Power-up with all multiplexer channels deselected.
  • Capacitance isolation when channel disabled.
  • No glitch on power-up.
  • Supports hot insertion.
  • 5 V tolerant inputs.
