PI4MSD5V9547 - 8-Channel I2C bus multiplexer

Datasheet Summary

Description

The PI4MSD5V9547 is an octal bidirectional translating multiplexer controlled by the I2C-bus.

The SCL/SDA upstream pair fans out to eight downstream pairs, or channels.

Only one SCx/SDx channel can be selected at a time, determined by the contents of the programmable control register.

Features

  • 1-of-8 bidirectional translating multiplexer.
  • I2C-bus interface logic.
  • Operating power supply voltage from 1.65V to 5.5V.
  • 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.
  • Active LOW reset input.
  • Channel selection via I2C bus.
  • Power-up with one channel on.
  • Capacitance isolation when channel disabled.
  • No glitch on power-up.
  • Supports hot insertion.
  • 5 V tolerant inp.
