Critique my circuit for chips with RESET pins
I'm using a 74LS192 DECADE counter which has a RESET pin on it. I've come up with a simple circuit that seems to work just fine for now: http://i.imgur.com/2RHZr.jpg Should I be concerned that my switch effectively shorts out the capacitor? We're only talking 5 volts at most here, which pretty low c...

Re: What is the "complement" to the 74LS154?
Thank you for the response.
After a little more digging, it seems that the '154 is primarily for memory addressing, so it's unlike the reverse of it was ever really needed.
Oh well.

What is the "complement" to the 74LS154?
I'd like to construct a multiplexed-demultiplexed control circuit. I've located specs easily enough on the 74LS154 (4-to-16 line decoder), but I can't seem to find what amounts to a 16-to-4 line encoder. I know about using a pair of 8-to-3's to get the equivalent function, but I'd like to know if a ...
