PCA8574D,518 General Description

The PCA8574D,518 is an 8-bit remote I/O expander from NXP, designed for general-purpose input/output applications. It is a versatile IC that allows users to expand or replace the existing GPIOs in their system with minimal added complexity. The device features two sets of eight open-drain outputs, each with individual address select inputs and interrupt outputs. This enables flexible control over individual I/O lines, as well as providing interrupt capabilities for notification of changes in the input status. The PCA8574D,518 is an ideal choice for applications requiring a large number of digital I/Os with interrupt capability.
