74ALS151
FEATURES
- 8-to-1 multiplexing
- On chip decoding
- Multi-function capability
- plementary outputs
- See 74ALS251 for 3-State version
DESCRIPTION
The 74ALS151 is a logic implementation of a single 8-position switch with the switch position controlled by the state of three select (S0, S1, S2) inputs. True (Y) and plementary (Y) outputs are both provided. The enable (E) is active-Low. When E is High, Y output is Low and the Y output is High regardless of all other inputs.
