Audio FX Remote Control - 74HC04/74HC14

Post by siwelk »

Re: Audio FX Remote Control

Can a 74HC14 be used in place of a 74HC04 for this application?
I ask only because we have a slew of these on-hand in our PLTW lab.

I haven't tried this combination, but it looks like it should work.

Thank you for the timely reply. My understanding led me to believe that it could work given the nature of the application.

I have ordered all the components for that project but was wondering if I could use what was laying around.
I guess I'll see when everything arrives. I will update this thread with the outcome of the compatibility test.

I was able to confirm that the 74HC14 works.
However, I am only getting about 4' of range with the FOB/receiver.

Can you speak of the expected range of the Simple RF M4 Receiver?

Any chance of getting some clarification re: the purported range for the RF receiver?

I've successfully controlled it from across the house, so maybe 30' or so.

I'd experienced range issues early on, and in that case it turned out to be the receiver voltage. What are you using to power the circuit? The receiver is happiest above 4 Volts.
