PCA6408APW,118 Description

Short technical summary and product information.

The PCA6408APW,118 is an 8-bit general purpose I/O expander from NXP Semiconductors, providing remote I/O expansion via the I2C-bus interface. This device is suitable for applications requiring additional I/Os while minimizing interconnections, such as in battery-powered mobile devices for interfacing with sensors or keypads.

 

Key electrical specifications include an operating voltage range of 1.65V to 5.5V and a clock frequency of up to 400 kHz. It features 8 I/O channels and supports both I²C and SMBus interfaces. The output type is Push-Pull, with current capabilities of 10mA for source and 25mA for sink. The device includes a Power-On Reset (POR) feature and an interrupt output.

 

Packaged in a 16-TSSOP, the PCA6408APW,118 is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The built-in level shifting feature makes it flexible for mixed-signal environments where communication between different I/O voltages is required.
