PI4MSD5V9543A - 2-Channel I2C Bus Switch

Datasheet Summary

Description

contents of the programmable control register.

Two upstream pair fans out to two downstream pairs, or the interrupt inputs, INT0 and INT1, one for each of the downstream pairs, are provided.

One interrupt output, INT, which acts as an AND of the two interrupt inputs, is provided.

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.
