QUAD 2-INPUT MULTIPLEXER
The MC74F157A is a high-speed quad 2-input multiplexer. Four bits of data
from two sources can be selected using the common Select and Enable in-
puts. The four buffered outputs present the selected data in the true (non-in-
verted) form. The F157A can also be used to generate any four of the 16 differ-
ent functions to two variables.
