Thanks >in advance. {slewrate} Good old analog 4051, 4052, 4053 family works well. Use the newer HC series - you would look for 74hc4052 for your application. This is only a dual 1-of-4 switch - use as many as you need and use the enable pin on each package to select the desired one. Only problem with that family is out-of-bound signals: if you go above Vdd or below Vee, you get crosstalk. dwayne -- Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 19 years of Engineering Innovation (1984 - 2003) .-. .-. .-. .-. .-. .-. .-. .-. .-. .- `-' `-' `-' `-' `-' `-' `-' `-' `-' Do NOT send unsolicited commercial email to this email address.
