PCA9536D,118 Description

Short technical summary and product information.

The NXP Semiconductors PCA9536D,118 is an 8-pin CMOS device designed for General Purpose Input/Output (GPIO) expansion in I2C-bus/SMBus applications. It provides 4 bits of I/O expansion, making it suitable for applications requiring additional control for components like ACPI power switches, sensors, push buttons, and LEDs.

This I/O expander operates within a voltage range of 2.3 V to 5.5 V and features 5 V tolerant I/Os. It supports clock frequencies up to 400 kHz and includes a Polarity Inversion register. The device defaults to 4 inputs with internal 100 kOhm pull-up resistors. Its fixed I2C-bus address allows for a single device on the bus.

The PCA9536D,118 is available in an 8-SOIC package, designed for surface mounting. It operates reliably within a temperature range of -40°C to 85°C. The device also features an internal power-on reset and noise filters on SCL/SDA inputs, ensuring stable operation.

Key features include 4-bit I2C-bus GPIO, low standby current, and robust ESD protection exceeding 2000 V HBM. This expander is a simple solution for adding I/O capabilities to embedded systems.
