TCA6416A Product details

Description

The TCA6416A is a 24-pin device that provides 16bits of general purpose parallel input/output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol.

Features

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 3 μA.
5-V Tolerant I/O ports.
400-kHz Fast I2C bus.
Hardware address pin allows two TCA6416A devices on the same I2C/SMBus bus.
Active-low reset input ( RESET).
Open-drain.
