TPT29548 - 8-channel I2C Switch

Description

The TPT29548 is a 1:8 bidirectional translating I2C switch.

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

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

Features

  • Bidirectional Translator of 1:8 I2C Switch.
  • Active-Low Reset Input.
  • Three address terminals, allowing up to 8 devices on the I2C Bus.
  • Operating Power-Supply Voltage Range of 2.3 V to 5.5 V.
  • Allows Voltage-Level Translation Between 2.5 V, 3.3 V, and 5 V 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 JESD 78.
  • ESD Protection Exceeds JESD 22.
  • 3.5 kV H.
