TCA9536BDTMR TI I2C I/O Expander | 8-X2SON (1.35x0.8) | 1.65-5.5V, 4 GPIO

Product Overview

The TCA9536BDTMR 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 (serial clock and serial data). The device features a 4-bit register for configuration (input or output) and a 4-bit output register. The TCA9536BDTMR operates from a 1.65V to 5.5V supply, making it suitable for low-voltage applications. It is available in a compact 8-pin X2SON package (1.35mm x 0.8mm), ideal for space-constrained designs.
