PCA6107DW TI I2C I/O Expander | 18-SOIC | 16-bit, 5.5V

Product Overview

The PCA6107DW is a 16-bit I2C-bus and SMBus I/O expander from Texas Instruments. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface (serial clock and serial data). The device features an 8-bit I/O port (P0–P7) and an 8-bit I/O port (P8–P15) that can be configured as inputs or outputs. The PCA6107DW operates from a 2.3 V to 5.5 V supply and supports up to 400 kHz I2C clock frequency. It is available in a compact 18-pin SOIC package, making it ideal for space-constrained applications.
