DESCRIPTION

The 74LVC2G14 is a high-performance, low-power,

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

advanced CMOS compatible TTL families.

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

feature allows the use of this device as translator in a

mixed 3.3 V and 5 V environment.

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 74LVC2G14A provides two inverting buffers with

Schmitt-trigger action. It is capable of transforming slowly

changing input signals into sharply defined, jitter-free

output signals.

CONDITIONS

VCC = 1.8 V; CL = 30 pF; RL = 1 kΩ

VCC = 2.5 V; CL = 30 pF; RL = 500 Ω

VCC = 2.7 V; CL = 50 pF; RL = 500 Ω

VCC = 3.3 V; CL = 50 pF; RL = 500 Ω

VCC = 5.0 V; CL = 50 pF; RL = 500 Ω

VCC = 3.3 V; notes 1 and 2

Notes

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

PD = CPD × VCC2 × fi × N + ∑(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;

∑(CL × VCC2 × fo) = sum of outputs.

2. The condition is VI = GND to VCC.
