74F132 Quad 2-Input NAND Schmitt Trigger

74F132 Quad 2-Input NAND Schmitt Trigger
General Description
The F132 contains four 2-input NAND gates which accept standard TTL input signals and provide standard TTL output levels. They are capable of transforming slowly changing input signals into sharply defined, jitterfree output signals. In addition, they have a greater noise margin than conventional NAND gates. Each circuit contains a 2-input Schmitt Trigger followed by level shifting circuitry and a standard FAST output structure. The Schmitt Trigger uses positive feedback to effectively speed-up slow input transitions, and provide different input threshold voltages for positive and negative-going transitions. This hysteresis between the positive-going and negative-going input threshold (typically 800mV) is determined by resistor ratios and is essentially insensitive to temperature and supply voltage variations.
