TCA9535DBT TI I2C I/O Expander | 24-SSOP | 16-Bit, 2.3V-5.5V

Product Overview

The TCA9535DBT is a 16-bit I/O expander from Texas Instruments (TI) designed for I2C bus applications. 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 a 16-bit configuration register, input/output port registers, and polarity inversion registers. The TCA9535DBT operates from a 2.3V to 5.5V supply and supports up to 400 kHz I2C clock frequency. It is available in a compact 24-SSOP package, making it suitable for space-constrained applications.
