Good Replacement for 4052 Analog Mux.

Started by Unknown January 11, 2015
Looking for a cost effective part that is better then the classic 4052 switch.

Requirements:

Rugged part that can handle being used by hobbyists.
Dip package preferred for customer replacement.
+/- 12 to 15V rails.
TTL Control
+/- 5V signal, DC to 3 KHz waveforms.

Better in what way?

I can't think of anything that will meet your requirements ("improved" 
CD4052 but not a CD4052).

If not for that last restriction, I would suggest a CD4052.  It does 
exactly what you're asking...

Solder some diodes onto the pins to improve ESD?  Beats the hell out of 
me.  Sure, there'll be lower resistance, much faster, possibly more ESD 
resistant devices out there, of similar layout, but they won't be "cost 
effective".  You're looking for a fourth side on a triangle...

2 x 4052 in parallel?
4052 is rather mismatched to the original circuit. A previous engineer switched to 4052 and its not doing well. Hence the request for alternatives.

Could you provide some specs about the circuit itself?

again give us a clue as to what way its mismatched
Turns out there are a few 74HC4052 variants shipped that can only handle a 5V upper rail.   Replaced it with DG409 and life is good.

Thanks All.
