The M74HC132 is an high speed CMOS QUAD2-INPUT SCHMITT NAND GATE fabricated withsilicon gate C2MOS technology.Pin configuration and function are identical tothose of the M74HC00.The hysteresis characteristics (around 20% Vcc)of all inputs allow slowly changing input signals tobe transformed into sharply defined jitter-freeoutput signals.All inputs are equipped with protection circuitsagainst static discharge and transient excessvoltage.
