TCAL9538DTUR TI I2C I/O Expander | 16-X2QFN (1.6x1.6) | 8-bit, 1.65-5.5V

Product Overview

The TCAL9538DTUR from Texas Instruments is a low-voltage 8-bit I²C and SMBus I/O expander with interrupt output and configuration registers. 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 1.65 V to 5.5 V, making it suitable for both 1.8 V and 3.3 V systems. Housed in a compact 16-X2QFN (1.6 mm x 1.6 mm) package, it is ideal for space-constrained applications.
