PCA9538BS,118 Description

Short technical summary and product information.

The PCA9538BS,118 is an 8-bit General Purpose Input/Output (GPIO) expander designed for I2C-bus/SMBus applications. Developed by NXP Semiconductors, this CMOS device enhances I/O capabilities for systems needing expansion for components like sensors, push-buttons, and LEDs.

 

Key features include 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 an active LOW interrupt output and an active LOW reset input. It consists of configuration, input port, output port, and polarity inversion registers, all accessible by the system master.

 

The PCA9538BS,118 is offered in a 16-HVQFN (4x4) package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The device provides 8 I/O pins that default to inputs and features a push-pull output type.
