PCF8575DB TI I2C I/O Expander | 24-SSOP | 16-bit, 400kHz

Product Overview

The PCF8575DB from Texas Instruments is a 16-bit I/O expander for I2C-bus applications, providing general-purpose remote I/O expansion for most microcontroller families via the I2C interface. It features a 16-bit quasi-bidirectional input/output (I/O) port, allowing easy expansion of digital I/O lines. The device operates from a 2.5V to 5.5V supply voltage and supports I2C clock frequencies up to 400kHz. Housed in a compact 24-SSOP package, it is ideal for space-constrained designs.
