Product Overview
The SN74AHC132N from Texas Instruments is a high-speed quad 2-input NAND gate with Schmitt-trigger inputs, housed in a 14-pin PDIP package. It operates over a wide supply voltage range of 2 V to 5.5 V, making it suitable for battery-powered and industrial applications. The Schmitt-trigger action at all inputs ensures clean switching even with slow or noisy input signals, providing hysteresis for improved noise immunity.
