General description
The 74LVC1G157 is a single 2-input multiplexer which select data from two data inputs (I0
and I1) under control of a common data select input (S). The state of the common data
select input determines the particular register from which the data comes. The output (Y)
presents the selected data in the true (non-inverted) form.
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 applications.
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.
Schmitt-trigger action at all inputs makes the circuit highly tolerant to slower input rise and
fall times.
