DESCRIPTION

The 74LVC1G14 is a high-performance, low-power,

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

advanced CMOS compatible TTL families.

The input can be driven from either 3.3 V or 5 V devices.

This feature allows the use of this device in a mixed

3.3 V and 5 V environment.

Schmitt-trigger action at the input 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 74LVC1G14 provides the inverting buffer function with

Schmitt-trigger action.

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.
