Product details

Description

The TCA6408A is a 16-pin device that provides 8-bits of general purpose parallel input/output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol.

Features

1 I2C to Parallel Port Expander.
Operating Power-Supply Voltage Range of 1.65 V to 5.5 V.
Allows Bidirectional Voltage-Level Translation and GPIO Expansion Between 1.8-V, 2.5-V, 3.3-V, and 5-V I2C Bus and P-Ports.
Low Standby Current Consumption of 1 μA.
5-V Tolerant I/O Ports.
400-kHz Fast I2C Bus.
Hardware Address Pin Allows Two TCA6408A Devices on the Same I2C/SMBus Bus.
Active-Low Reset (RESET) Input.
Open-Drain.
