Product Description:
Pericom Semiconductor鈥檚 PI74FCT series of logic circuits are
produced in the Company鈥檚 advanced 0.8 micron CMOS
technology, achieving industry leading speed grades.
PI74FCT132 consists of four 2-input NAND gates that are able to
transform slowly changing input signals into highly defined,
jitter-free output signals.
Each gate contains a 2-input Schmitt trigger which uses positive
feedback to speed-up slow input transitions, and offer different
input threshold voltages for positive and negative-going transitions.
Resistor-ratios are used to determine this hysteresis between the
positive-going and negative-going input threshold.
