MC14419 - 2-Of-8 Keypad-To-Binary Encoder
MCl~19 2-OF-8 KEYPAD-TO-BINARY ENCODER The MC14419 is designed for phone dialer system applications, but finds many applications as a keypad-to-binary encoder.
The device con- tains a 2-of-8 to binary encoder, a strobe generator, and an illegal state detector.
The encoder has four row inputs and four column inputs, and is designed to accept inputs from 16 keyswitches arranged in a 4x 4 matrix.
For an output on the four data lines, one and only one row along with one and only one column i
