Quad 2-input NAND Schmitt trigger
74HC/HCT132
FEATURES
Output capability: standard
ICC category: SSI
GENERAL DESCRIPTION
The 74HC/HCT132 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).
They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT132 contain four 2-input NAND gates which accept standard input signals. They are capable of
transforming slowly changing input signals into sharply defined, jitter-free output signals.
The gate switches at different points for positive and negative-going signals. The difference between the positive voltage
VT+ and the negative voltage VT is defined as the hysteresis voltage VH.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25 °C; tr =tf = 6 ns
Notes
1. CPD is used to determine the dynamic power dissipation (PD in W):
PD =CPD × VCC2 × fi +∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC 1.5 V
