WebMay 25, 2024 · In logic design, a pullup/pulldown is intended to set a default input, as a floating input on CMOS logic will oscillate wildly and draw a lot of power as a result (CMOS draws power at the transition unless driving some current-drain output). And of course, a wildly-fluctuation input is not desirable for logic.
