IO Expan

NXP’s general-purpose input/output (GPIO) expanders are a simple, cost-effective way to monitor and control several peripheral signals. They connect to a microprocessor via a bidirectional serial interface and the portfolio span from 4 I/Os to 40 I/Os. Consequently, they make it easy for designers to add extra I/O to their design and thereby free up the microprocessor’s GPIO for other, more important functions. NXP is the industry leader in serial-interface I/O expanders and offers a broad selection of cost effective, easy-to-use options with different number of I/Os, various output-drive current and voltage tolerances, and the devices come in a wide range of features and package options. The portfolio includes devices which can drive up to 25 mA per output. NXP I/O expanders are found in a multitude of applications including computing, mobile, and industrial control.
