The SN54 / 74LS132 contains four 2-Input NAND Gates which accept stan-
dard TTL input signals and provide standard TTL output levels. They are ca-
pable of transforming slowly changing input signals into sharply defined, jitter-
free output signals. Additionally, they have greater noise margin than
conventional NAND Gates.
Each circuit contains a 2-input Schmitt trigger followed by a Darlington level
shifter and a phase splitter driving a TTL totem pole output. The Schmitt trigger
uses positive feedback to effectively speed-up slow input transitions, and
provide different input threshold voltages for positive and negative-going tran-
sitions. This hysteresis between the positive-going and negative-going input
thresholds (typically 800 mV) is determined internally by resistor ratios and is
essentially insensitive to temperature and supply voltage variations. As long
as one input remains at a more positive voltage than VT+ (MAX), the gate will
respond to the transitions of the other input as shown in Figure 1.
