TCA9535PWR Description

Short technical summary and product information.

The TCA9535PWR from Texas Instruments is a versatile 16-bit general-purpose parallel input/output (I/O) expander. It communicates via the I2C or SMBus protocol, supporting clock frequencies up to 400 kHz.

 

This device operates within a wide power supply voltage range of 1.65V to 5.5V, making it suitable for various applications. It features configuration registers for input/output selection, an input port, an output port, and a polarity inversion register. The TCA9535PWR includes an open-drain active-low interrupt output and 5V tolerant I/O ports.

 

Packaged in a 24-TSSOP, the TCA9535PWR is designed for surface mount applications. It operates across a temperature range of -40°C to 85°C. The part offers latched outputs with high-current drive capability, suitable for directly driving LEDs. Addressability is managed by three hardware address pins, allowing up to eight devices on the bus.
