DESCRIPTION
The 74LVC2G126 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.
These feature allows the use of these devices as
translators 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 74LVC2G126 provides a dual non-inverting buffer/line
driver with 3-state output. The 3-state output is controlled
by the output enable input (pin nOE). A LOW-level at
pin nOE causes the output to assume a high-impedance
OFF-state. Schmitt-trigger action at all inputs makes the
circuit highly tolerant for slower input rise and fall times.

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 load switching outputs;
∑(CL × VCC2 × fo) = sum of outputs.
2. The condition is VI = GND to VCC.
