PI4MSD5V9544A - 4 Channel I2C bus Multiplexer

Datasheet Summary

Description

The PI4MSD5V9544A is a 1-of-4 bidirectional translating multiplexer, controlled via the I2C bus.

The SCL/SDA upstream pair fans out to four SCx/SDx downstream pairs, or channels.

Features

  • 1-of-4 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.
