74LVC157ABQ-74LVC157AD
74LVC157A; Quad 2-input multiplexer
1. General description
The 74LVC157A is a quad 2-input multiplexer which select four bits of data from two
sources under the control of a common select input (S). The four outputs present the
selected data in the true (non-inverted) form. The enable input (E) is active LOW. When
pin E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all the other
input conditions. Moving the data from two groups of registers to four common output
buses is a common use of the 74LVC157A. The state of the common data select input (S)
determines the particular register from which the data comes. It can also be used as
function generator.
It is useful for implementing highly irregular logic by generating any 4 of the 16 different
functions of two variables with one variable common.
The device is the logic implementation of a 4-pole, 2-position switch, where the position of
the switch is determined by the logic levels applied to pinS.
Inputs can be driven from either 3.3 V or5 V devices. This feature allows the use of these
devices as translators in mixed 3.3 V and5 V applications.
