1. General description
The 74LVC157A is a quad 2-input multiplexer. The device features select (S) and enable E inputs.
A HIGH on S selects data source 1, a LOW data source 0. A HIGH on E forces all the outputs (1Y
to 4Y) LOW. 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.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
