PI4MSD5V9548A - 8-Channel I2C Bus Switch

General Description

The DIODES™ PI4MSD5V9548A is an octal bidirectional translating switch controlled via the I2C bus.

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

Key Features

  • 1-of-8 Bidirectional Translating Switch.
  • I2C-bus Interface Logic.
  • Operating Power Supply Voltage from 1.65V to 5.5V.
  • Allows Voltage Level Translation between 1.2V, 1.8V, 2.5V, 3.3V and 5V buses.
  • Low Standby Current.
  • Low Ron Switches.
  • Active LOW Reset Input.
  • Channel Selection via I2C bus.
  • Power-up with all switches channels deselected.
  • Capacitance Isolation when channels el disabled.
  • No Glitch on power-up.
  • Supports hot insertion.
  • 5.
