TCA9536AQDTMRQ1 TI I2C I/O Expander | 8-X2SON (1.35x0.8) | 1.65-5.5V, 4 GPIO

Product Overview

The TCA9536AQDTMRQ1 is a low-voltage, 4-bit I2C and SMBus I/O expander from Texas Instruments, designed for automotive applications. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface. The device features a wide operating voltage range of 1.65V to 5.5V, making it suitable for both 1.8V and 3.3V systems. Housed in a compact 8-X2SON package (1.35mm x 0.8mm), it is ideal for space-constrained designs. The TCA9536AQDTMRQ1 is AEC-Q100 qualified for automotive applications.
