14-Bit SPI I/O Expander with Agile I/O Features
PCAL9714 Receive alerts
The PCAL9714 is an ultra-low voltage 14-bit I/O expander and translator with SPI interface and is ideal for a wide range of applications that require expansion of inputs and outputs to their existing micro and reduces design cycle time. Integrated Agile I/O features further enables flexible and configurable designs with push-pull or open-drain outputs, interrupt status registers, four different output drive strengths, enable and resistor selector for pull-up and pull-down resistors, and interrupt mask options.
