PCF8575CPW TI I2C I/O Expander | 24-TSSOP | 16-bit, 2.3V-5.5V

Product Overview

The PCF8575CPW from Texas Instruments is a 16-bit I/O expander for I2C-bus applications, providing general-purpose remote I/O expansion via a two-line bidirectional bus. It operates from 2.3V to 5.5V and features interrupt output, open-drain interrupt line, and three hardware address pins allowing up to 8 devices on the same bus. Housed in a compact 24-TSSOP package, it is ideal for systems where additional I/O ports are needed without increasing pin count.
