1. General description
2. Features
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 of slower input rise and fall times.
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 I
circuitry disables the output, preventing the damaging backflow current through the device
when it is powered down.
