TCA9536DTMR TI I/O Expanders

The TCA9536DTMR is a versatile 4-bit I/O expander from Texas Instruments specifically designed for operation with a voltage range of 1.65V to 5.5V, making it compatible with a wide range of microcontroller families via the I2C interface. This allows for easy remote I/O expansion, providing increased flexibility for system controllers in various applications. The device supports 1-MHz Fast Mode Plus I2C clock frequency for high-speed data transfer. Key features include configuration registers for I/O direction control, an interrupt pin for change detection, and high-speed I/O operation ensuring reliable and efficient system design. With 4 I/O lines, address selection for up to 4 devices on the same bus, and low power consumption, the TCA9536DTMR is ideal for space-constrained applications requiring minimal I/O expansion. Housed in an 8-pin XFDFN (DTM) package, it operates over -40°C to 125°C. Applications include portable electronics, wearables, mobile devices, sensor interfaces, and any GPIO-limited system requiring a small number of additional I/O lines in a compact package.
