8-Input Multiplexer

with 3-State Outputs

The TTL/MSI SN74LS251 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 LS251 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

• Inverting and Non-Inverting 3-State Outputs

• Input Clamp Diodes Limit High Speed Termination Effects
