The 74F157A is a high-speed quad 2-input multiplexer. It can select four bits of data from two sources using the common Select and Enable inputs. The four outputs present the selected data in non-inverted form. The 74F157A can also be used to generate any four of the 16 different functions to two variables. The device is available in Tape and Reel packaging.
This document is a datasheet for the Fairchild Semiconductor 74F157A, a high-speed quad 2-input multiplexer. The device allows four bits of data from two sources to be selected using common Select and Enable inputs, presenting the selected data in true (non-inverted) form. It can also be utilized to generate any four of the 16 different logic functions for two variables.
| Propagation Delay (Typical) | 40 ns |
