NXP PCA9674APW118 8-bit I/O Expander
The PCA9674APW118 is a reliable 8-bit remote I/O expander designed for industrial applications, utilizing Fm+ I2C-bus with interrupt support. It features a 1 MHz I2C interface for high-speed data transfer, supporting PWM dimming, and can drive up to 30 mA per device, enabling the connection of multiple devices without buffers. With three hardware address inputs and an active LOW interrupt output, it allows seamless monitoring of input changes. Its small package options and low current consumption make it ideal for mobile and industrial control systems. Power-on reset initializes all I/Os as inputs with weak internal pull-ups, ensuring safe startup conditions. The device supports up to 126 expanders on the same I2C-bus, providing up to 1008 I/O points. It is suitable for LED signs, keypads, industrial control, medical equipment, and more.
