PCAL9535APW,118 Description

Short technical summary and product information.

The PCAL9535APW,118 from NXP Semiconductors is a low-voltage, 16-bit General Purpose Input/Output (GPIO) expander designed for I2C-bus/SMBus applications. It provides a flexible solution for systems requiring additional I/Os, such as ACPI power switches, sensors, push buttons, and LED control.

 

This device supports a wide operating voltage range from 1.65 V to 5.5 V, enabling compatibility with modern microprocessors and microcontrollers. It includes features like programmable output drive strength, latchable inputs, programmable pull-up/pull-down resistors, and a maskable interrupt. The PCAL9535APW,118 has an open-drain interrupt output and 25 mA sink capabilities for directly driving LEDs.

 

Packaged in a 24-TSSOP, the PCAL9535APW,118 is suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C and communicates via I2C/SMBus at clock frequencies up to 400 kHz. The device also features a power-on reset function.
