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