74F157A
Quad 2-Input Multiplexer
General Description
The F157A is a high-speed quad 2-input multiplexer. Four
bits of data from two sources can be selected using the
common Select and Enable inputs. The four outputs
present the selected data in the true (non-inverted) form.
The F157A can also be used to generate any four of the 16
different functions to two variables.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
