I need to interface to the expansion connectors on the experimenter kit (specifically the audio expansion connector, J30). And I need logic gates (AND, OR, FLIP-FLOPS) to interface with that.
What logic family should I use for the interface? (TTL? CMOS? Low voltage CMOS? etc.)
At what voltage? (5V? 3.3V? 1.8V?)
Thanks for your help.
