PCAL6408ABSHP Description

Short technical summary and product information.

The PCAL6408ABSHP is an 8-bit general-purpose I/O expander from NXP Semiconductors, designed for remote I/O expansion via the I2C-bus interface. It supports a wide operating voltage range from 1.65V to 5.5V, enabling seamless communication in mixed-signal environments with incompatible I/O voltages due to its built-in level shifting feature.

This I/O expander operates at a clock frequency of up to 400 kHz and features 8 I/O pins with configurable output types (Open Drain, Push-Pull). It includes an interrupt output and Power-On Reset (POR) functionality. The device is supplied in a 16-HVQFN (3x3) package, suitable for surface mounting.

Ideal for applications requiring additional I/Os with minimal interconnections, such as battery-powered mobile devices, interfacing with sensors, push buttons, and keypads. The PCAL6408ABSHP simplifies interconnection between microcontrollers and peripherals operating at different voltage levels.
