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 . |
