Dear all,
I have to design a circuit with multiplexer to change the ttl logic outputs. I have a TTL output from a microcontroller and I need to do something like this. Output port goes to RF module if I select 0 and output port goes to max232 for pc connection if I select 1. Choosing select 0 and 1 will be with jumper. Can you suggest me an IC which you used before?
Why don't you look at a multiplexer IC manufacture for a selection guide?
Or at a distributor.
Then you will see that there are hundreds...and you need to input all the informations we need to ask for, too.
Like power supply, signal voltage range, signal frequency range, ON resistance....
