The MAX7359 two-wire interfaced, low-EMI key-switch controller detects multiple key press and release events on up to 64 keys—by generating and storing individual key codes in a FIFO register for each press and release to allow the monitoring of multiple key-switch events.
The part provides up to seven open-drain logic outputs that can be configured to drive LEDs. Available in a 24-pin TQFN package, the device operates over the -40° to 85°C temperature range. (From $1.70 ea/1,000—available now.)
