74F158A Quad 2-Input Multiplexer General Description The F158A is a high speed quad 2-input multiplexer. It selects four bits of data from two sources using the com- mon 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 vari- ables.

Frequently Asked Questions
How many data bits can the F158A select?
It selects four parallel bits of data from two distinct sources.
What is the operating voltage range for this chip?
The recommended Supply Voltage (VCC) is between +4.5V and +5.5V.
How does the Enable input (E) control the outputs?
When E is HIGH, all four output pins (Z) are forced high regardless of other inputs.
What package types are available for ordering this component?
Available physical packages include SOIC (M16A), SOP (M16D), and PDIP (N16E).
