16, 20-Key Encoder

General Description These 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 pullup devices which permit switches with up to 50 kXon
