DM54S251 DM74S251 TRI-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 TRI-STATE output The strobe must be at a low logic level to enable these devices The TRI-STATE outputs permit direct connection to a common bus When the strobe input is high both outputs are in a high-impedance state in which both the upper and lower
transistors of each totem pole output are off and the output neither drives nor loads the bus significantly When the strobe i...
