Abstract
In a personal computer system utilizing both a main power supply and an auxiliary power supply, the input and output signal lines of auxiliary powered components are selectively isolated from components powered solely by the main power supply. Gating circuitry and buffer circuitry, controlled by various enable signals, are used to isolate the signal lines. External pull-down or pull-up resistors are no longer required, which frees up printed circuit board area for other components and conserves board space in the computer system.
