Why are integrated circuits powered by low voltage and high

Apr 22, 2020 · Pros for high voltage. Reliability. If you have a poor-quality circuit (such as a 7-mile thin copper telephone wire), itmuch easier to reliably tell the difference between 48V and 0, but darn near impossible to tell apart 1V from 0V. Basically high voltage "just works" no matter what. Thatpretty much it.Get price
