The MC74AC158/74ACT158 is a high-speed quad 2-input multiplexer. It selects four bits of data from two sources using the common Select and Enable inputs. The four buffered outputs present the selected data in the inverted form. The MC74AC158/74ACT158 can also be used as a function generator.
This document provides technical specifications for the MC74AC158 and MC74ACT158 devices, which are high-speed quad 2-input multiplexers. These components select four bits of data from two sources using common Select and Enable inputs and present the selected data in an inverted form at the outputs.
| Outputs Source/Sink Current | 24 mA |
|---|---|
| Operating Ambient Temperature | -40 to +85 °C |
The Enable input (E) is active-LOW; when E is HIGH, all outputs are forced HIGH regardless of other inputs.
The four buffered outputs present the selected data in the inverted form.
