The PCAL9722 is an ultra-low voltage 22-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 enable 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.
Participating products are available for a minimum of 10 years. Designated participating products developed for the automotive, telecom and medical segments are available for a minimum of 15 years.
