SN7AHC132 4-Channel 4-Input NAND Gate Texas Instruments SN7AHC132 4-Channel 4-Input NAND Gate is a quadruple positive-NAND gate designed for 2V to 5.5V VCC operation. This device performs the Boolean function Y = A × B or Y = A + B in positive logic. Schmitt-trigger inputs of the Texas Instruments SN7AHC132 provide added noise immunity and support for slow input signal transitions.
