    Using a simple Dual D FF as indicated and using a Schmitt trigger with the "momentary on" pushbutton w/debouncing; I want to latch/drive 2 sections of a 4066 quad bilateral switch for the switching of line level signals. Tho /Q is tacked to D. Can /Q be tapped also to a switch actuator of the 4066? Or would it be better using Master/Slave configuration? The purpose is to switch from one active signal path to another (A/B switch). This will be multiplied into a digital signal switching matrix for my guitar rig. Is there a particular Dual D FF IC that would be recommended? Will the Schmitt give sufficient "edge" to toggle the state? I would prefer to have leading edge vs trailing for timing reasons.

    It's been a long time away from design work, so forgive my ignorance or "thickness". I've a lot of re-studying to do on the basics....

    Thx!

    A 4013 should work fine. CMOS has no problem driving several other CMOS load. See fan-out on the data sheet.

    But no problem with half tapping /Q for D as well as the 4066 then?
