PCA6408ABSHP Description

Short technical summary and product information.

The PCA6408ABSHP from NXP Semiconductors is an 8-bit general purpose I/O expander designed for remote I/O expansion via the I2C-bus interface. It is suitable for applications requiring additional I/Os while minimizing interconnections, such as in battery-powered mobile devices for interfacing with sensors or keypads.

 

This I/O expander supports a wide VDD range of 1.65 V to 5.5 V, enabling seamless communication between low-voltage microprocessors and peripherals operating at different voltage levels due to its built-in level shifting feature. It operates at a maximum clock frequency of 400 kHz and provides 8 I/O pins. The device includes configuration, input, output, and polarity inversion registers, with I/Os defaulting to inputs at power-on.

 

The PCA6408ABSHP is available in a 16-HVQFN (3x3) package and is surface-mount compatible. It operates within a temperature range of -40°C to 85°C. The device also features an open-drain interrupt output to signal the system master of input state changes without constant I2C-bus communication.
