1. General description
The 74LVC1G126 is a single buffer/line driver with 3-state output. 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.
