Quad. 2-to-1-line Data Selectors/Multiplexers(with noninverted 3-state outputs)

Description The large output drive capability coupled with the 3-state feature make this device ideal for interfacing with bus lines in a bus organized system. When the output control input line is taken high, the outputs of all four multiplexers are sent into a high impedance state. When the out
