PCF8575DBR TI I/O Expander | 24-SSOP | 16-bit, I2C

Product Overview

The PCF8575DBR 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)). It operates from a 2.5V to 5.5V supply and features 16 quasi-bidirectional I/O ports. The device includes an interrupt output (INT) that can be connected to the microcontroller's interrupt input, allowing the system to be notified when input data changes. The PCF8575DBR is available in a compact 24-SSOP package, making it ideal for space-constrained designs.
