Summary in PDF File


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 contains 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 input line must be activated All other combinations are suppressed by the illegal state detector to eliminate false data output The strobe generator produces a strobe pulse when any of the 10 keys corresponding output to numerals O through erroneous 9 are depressed The strobe can be used to eliminate data entry due to contact tt contact bounce has settled and 80 clock pulses have occurred the outt put will be a single strobe pulse equal in width to that of the clock low state The strobe generator will output one and only one pulse eq ch j time a numerical key is depressed After the pulse has occurred x se and bounce due to contact break will not cause another stro iQQ15 5 ms a t th last With a 16 kHz input clock frequency the pulse
