INTEGRATED-CIRCUIT LOGIC FUNCTIONS
INTEGRATED-CIRCUIT LOGIC FUNCTIONSLogic circuits are implemented with either bipolar or MOS technologies. Bipolar logic circuits encompass a variety of different basic "families," each with its unique advantages and limitations. These various families are divided into two generic categories: saturated logic and nonsaturated logic. In saturated-logic designs, the transistor (acting as a switch) is driven from the cutoff condition to the saturated condition by the input signal. In nonsaturated logic, the transistor is not switched from full off to full on but swings above and below a specified reference level. Thus, nonsaturated logic avoids some of the inherent transistor time delays associated with saturated-mode switching but pays for the resulting improvement in switching speed with increased power…
