ABSTRACT:
A CMOS device having many output channels at least one of which channel includes a first pair of pull-up/pull-down of transistors between a "noisy Vcc and noisy ground", a second pair of pull-up/pull-down of transistors between a "quiet Vcc and quiet ground", and logic to switch the transistor pairs such that initial switching of an output is powered by the noisy Vcc and ground, and maintenance of an output state is powered by the quiet Vcc and ground. Quiescent channels are decoupled from active channels and will hold their assigned output levels.
