[sdiy] Quick question about 4066/4016 switches

[Harry Bissell]

forget the passive approach, IMHO. Its too slow for that frequency. I'd use a transistor
level shifter...

A PIC is providing the logic signal, and I'm going to use the switch for PWM, so it'll be switching at 40 to 80KHz. Haven't decided exactly yet.

Thanks,
