SN74LS132

Quad 2-Input
Schmitt Trigger NAND Gate

The SN74LS132 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, 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 transitions. 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 V

T+

(MAX), the gate will respond to the transitions of the other input as
shown in Figure 1.
