DESCRIPTION
The 74LV132 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT132.
The 74LV132 contains 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.

GND = 0V; Tamb = 25°C; tr = tf v2.5 ns
SYMBOL
PARAMETER
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.

Notes 1 and 2
NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW)
PD = CPD VCC2 fi )S (CL VCC2 fo) where:
fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
S (CL VCC2 fo) = sum of the outputs.
2. The condition is VI = GND to VCC
