M74C923 - MM74C923

www.DataSheet4U.com The MM74C922 and MM74C923 CMOS key encoders provide all the necessary logic to fully encode an array of SPST switches.

The keyboard scan can be implemented by either an external clock or external capacitor.

These encoders also have on-chip pull-up devices which permit switches wi
