The 74F158A is a high speed quad 2-input multiplexer from Fairchild Semiconductor Corporation. It selects four bits of data from two sources using the common Select and Enable inputs. The four outputs present the selected data in the inverted form. The F158A can also generate any four of the 16 different functions of two variables.
This document is a datasheet for the Fairchild 74F158A, a high-speed quad 2-input multiplexer. The device selects four bits of data from two sources using common Select and Enable inputs and presents the selected data in an inverted form at the outputs. It is also capable of generating four of the 16 different functions of two variables.
The Enable input is active LOW; when HIGH, all outputs are forced HIGH regardless of other inputs.
It selects four bits of data from two sources.
