All:
Does anyone have a PDF copy of the data sheet for the General
Instruments AY5-2376 ASCII keyboard encoder chip?
Hi Rich,
I have a small (2 page) datasheet for an SMC KR2376-xx keyboard
encoder which is probably a compatible device (to check, VCC is on
pin 1, Ground is on pin 17, and the keyboard matrix connects to
21-31 (inputs) and 32-39 (outputs).
As noted above, it's only 2 pages. It gives you the pinout, typical
connection diagram, character matrix assignment chart and some
waveform charts.
If this is of use to you, I can scan it for ya.
Regards,
Dave
