74LS251

3-STATE 1-of-8 Line Data Selector/Multiplexer

General Description These data selectors/multiplexers contain full on-chip binary decoding to select one-of-eight data sources, and feature a strobe-controlled 3-STATE output. The strobe must be at a low logic level to enable these devices. The 3-STATE outputs permit direct connection to a comm

74LS251

LOW POWER SCHOTTKY

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 outp

3-STATE Data Selector/Multiplexer

General Description Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully comple mentary, on-chip, binary decoding data selection to the AND-OR gates. Separate output control inputs are pro vided for each of the two four-line sections.
