Quadruple 2-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs

These devices are designed to multiplex signals from four-bit data sources to four-output data lines in bus-organized systems. The 3-state outputs will not load the data lines when the output control pin (G) is at a high-logic level.
Series 54LS and 54S are characterized for operation over the full military temperature range of -55C to 125C; Series 74LS and 74S are characterized for operation from 0C to 70C.
