8-INPUT MULTIPLEXER
The TTL / MSI SN54 / 74LS151 is a high speed 8-input Digital Multiplexer. It provides, in one package, the ability to select one bit of data from up to eight sources. The LS151 can be used as a universal function generator to generate any logic function of four variables. Both assertion and negation outputs are provided.
- Schottky Process for High Speed
- Multifunction Capability
- On-Chip Select Logic Decoding
- Fully Buffered plementary Outputs
- Input Clamp Diodes Limit High Speed Termination Effects
