Quadruple 2-line to 1-line data selectors/multiplexers featuring 3-state outputs. This integrated circuit offers 4 independent multiplexer circuits, each with 2 input lines and 1 output line. Operating with a single supply voltage range of 4.5V to 5.5V, it provides a bandwidth of 75MHz and a propagation delay of 12ns. The component is housed in a 16-PDIP through-hole package, with dimensions of 19.3mm length, 6.35mm width, and 4.57mm height. It supports a high level output current of 24mA and a low level output current of 2.6mA, with a maximum power dissipation of 1.1W.
