54F/74F132 Quad 2-Input NAND Schmitt Trigger
This document is a datasheet for the 54F/74F132, a quad 2-input NAND gate with Schmitt trigger inputs. The device accepts standard TTL input signals and provides standard TTL output levels, transforming slowly changing input signals into sharply defined, jitter-free output signals. It features a hysteresis between positive and negative-going input thresholds determined by resistor ratios, making it insensitive to temperature and supply voltage variations.
