PCAL6408AHKX Description

Short technical summary and product information.

The PCAL6408AHKX from NXP Semiconductors is an 8-bit general-purpose I/O expander designed for remote I/O expansion via the I2C-bus interface. It supports a wide VDD range of 1.65 V to 5.5 V, enabling seamless communication between microcontrollers and peripherals operating at different voltage levels due to its built-in level shifting feature.

 

This I/O expander operates at clock frequencies up to 400 kHz and features both open-drain and push-pull output types. It includes an interrupt output and POR (Power-On Reset) functionality. The device is available in a 16-XQFN surface-mount package.

 

Ideal for applications requiring additional I/Os with minimal interconnections, such as in battery-powered mobile devices, the PCAL6408AHKX simplifies interfacing with sensors, push buttons, and keypads. Its flexible configuration options and level translation capabilities make it suitable for mixed-signal environments.
