TCA6416PW TI I2C I/O Expander | 24-TSSOP | 16-bit, 1.65-5.5V

Product Overview

The TCA6416PW from Texas Instruments is a 16-bit I2C-bus and SMBus I/O expander designed for 1.65-V to 5.5-V VCC operation. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface (serial clock (SCL) and serial data (SDA)). The device features an interrupt output (INT) that can be connected to the interrupt logic of the microcontroller, sending a signal when any input state differs from its corresponding input port register state. The TCA6416PW is available in a 24-pin TSSOP package, making it suitable for space-constrained applications.
