Part MC14419
Description 2-Of-8 Keypad-To-Binary Encoder
Feature MCl~19 2-OF-8 KEYPAD-TO-BINARY ENCODER The MC14419 is designed for phone dial er system applications, but finds many applications as a keypad-to-binary enc oder.
The device con- tains a 2-of-8 t o binary encoder, a strobe generator, a nd an illegal state detector.
The enco der has four row inputs and four column inputs, and is designed to accept inp uts from 16 keyswitches arranged in a 4 x 4 matrix.
For an output on the four data lines, one and only one row along with one and only one column input lin e must be activated.
All other combina tions are suppressed by the illegal sta te detector to .
