PCA6416A - 16-bit I2C-bus/SMBus I/O expander

📥 Download Datasheet

General Description

The PCA6416A is a 16-bit general purpose I/O expander that provides remote I/O expansion for most microcontroller families via the I2C-bus interface.

NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in battery-powered mobile applications for interfacing to sensors, push buttons, keypad, etc.

In addition to providing a flexible set of GPIOs, it simplifies interconnection of a processor running at one voltage level to I/O devices operating at a different (usually higher) voltage level.
