PCF8575RGER TI I2C I/O Expander | 24-VQFN (4x4) | 16-bit, 400kHz

Product Overview

The PCF8575RGER from Texas Instruments is a 16-bit I/O expander for I2C-bus applications, providing general-purpose remote I/O expansion via the two-line bidirectional I2C bus (serial clock (SCL) and serial data (SDA)). The device features a 16-bit quasi-bidirectional input/output (I/O) port, allowing each bit to be configured as input or output without the need for control registers. The PCF8575RGER operates from a 2.3V to 5.5V supply voltage and supports I2C clock frequencies up to 400 kHz. It is available in a compact 24-pin VQFN (4x4 mm) package, making it ideal for space-constrained applications.
