TPT29545 - 4-channel I2C Switch

Description

The TPT29545 is a 1:4 bidirectional translating I2C switch.

The SCL/SDA upstream pair fans out to four downstream channels.

Any single SCn/SDn channel or combination of channels can be selected, determined by the programmable control register.

Features

  • Bidirectional Translator of 1:4 I2C Switch.
  • Four Active-Low Interrupt Inputs.
  • Active-Low Interrupt Output and Active-Low Reset Input.
  • Two Address Terminals, Allowing up to Four Devices on the I2C Bus.
  • Operating Power-Supply Voltage Range of 2.3 to 5.5V.
  • Allow Voltage-Level Translation among 2.5V, 3.3V, and 5V Buses.
  • Support Standard Mode and Fast Mode I2C Devices，0 to 400 kHz Clock Frequency.
  • Low RON Switches.
  • Latch-Up Performance Exceeds 200 mA per.
