1. General description
The 74LVC2G126 is a dual buffer/line driver with 3-state outputs controlled by the output enable
inputs (nOE). Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of
these devices as translators in mixed 3.3 V and 5 V environments.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry
disables the output, preventing the potentially damaging backflow current through the device when
it is powered down.
