PCA9536TK,118 Description

Short technical summary and product information.

The PCA9536TK,118 from NXP Semiconductors is an 8-pin CMOS device providing 4 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications. This IO expander is suitable for applications requiring additional I/O for components like ACPI power switches, sensors, push buttons, and LEDs.

 

Key features include a configurable 4-bit I/O port, an operating power supply voltage range of 2.3 V to 5.5 V, and 5 V tolerant I/Os. The device supports a clock frequency up to 400 kHz and includes a polarity inversion register for active HIGH or LOW operation. It defaults to 4 inputs with internal 100 kΩ pull-up resistors.

 

The PCA9536TK,118 is available in an 8-HVSON (3x3) package, designed for surface mount installation. It operates within a temperature range of -40°C to 85°C. The device also incorporates an internal power-on reset and noise filters on SCL/SDA inputs, ensuring reliable operation.

 

This IO expander is ideal for systems needing simple I/O expansion without complex interface requirements. Its fixed I2C-bus address allows for a single device on the bus, simplifying system design.
