PCA9535APW,118 Description

Short technical summary and product information.

The PCA9535APW,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 simple solution for systems needing additional I/Os, such as for ACPI power switches, sensors, push buttons, and LED control.

 

This I/O expander features a wide operating supply voltage range of 1.65 V to 5.5 V, allowing it to interface with modern microprocessors and microcontrollers. It supports a 400 kHz Fast-mode I2C-bus and includes an open-drain interrupt output that signals changes in input states to the system master. The device has latched outputs with 25 mA sink capabilities, suitable for directly driving LEDs.

 

The PCA9535APW,118 is supplied in a 24-TSSOP package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The device includes a power-on reset function and is pin-compatible with other industry-standard devices like the PCA9535.
