| Description | 16/ 20-Key Encoder |
|
|
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 kX on resistance to be used No diodes in the switch array are needed to eliminate ghost switches The internal debounce circuit needs only a single...
