TCA9536DGKR TI I2C I/O Expander | 8-VSSOP | 1.65-5.5V, 4 GPIO

Product Overview

The TCA9536DGKR is a low-voltage 4-bit I2C and SMBus I/O expander from Texas Instruments. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface. The device features a 4-bit configuration register for input, output, or polarity inversion selection. The TCA9536DGKR operates from 1.65V to 5.5V, supports up to 400 kHz I2C clock frequency, and is available in a compact 8-VSSOP package. It is ideal for applications where additional I/O lines are needed while minimizing board space and power consumption.
