I/O expanders extend power management flexibility

Sunnyvale, Calif. – Maxim’s eleven new 8- and 16-port general-purpose input/output (GPIO) and
LED drivers, the MAX7319-MAX7329, are serial-bus-controlled devices that support general computing, communication, consumer, industrial, and medical applications, from driving display and keypad backlights, function and status indicators and RGB fun lights to battery- and signal-strength indicator LEDs. These expanders are feature and software compatible with each other, so any combination of the 16-port and 8-port devices can be used together for applications requiring more I/Os.
