Good Replacement for 4052 Analog Mux.

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.
