DESCRIPTION

The 74LVC1G32 is a high-performance, low-power,

low-voltage, Si-gate CMOS device, superior to most

advanced CMOS compatible TTL families.

Input can be driven from either 3.3 V or 5 V devices. This

feature allow the use of these devices in a mixed

3.3 V and 5 V environment.

Schmitt-trigger action at all inputs makes the circuit

tolerant for slower input rise and fall time.

This device is fully specified for partial power-down

applications using Ioff. The Ioff circuitry disables the output,

preventing the damaging backflow current through the

device when it is powered down.

The 74LVC1G32 provides the single 2-input OR function.

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW).

PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in Volts;

N = total switching outputs;

Σ(CL × VCC2 × fo) = sum of the outputs.

2. The condition is VI = GND to VCC.
