HD74LS257

Quadruple 2-line-to-1-line Data Selectors / Multiplexers (with not inverted 3-state outputs)

This multiplexer features three-state outputs that can interface directly with and drive data lines of bus-organized systems. With all but one of the common outputs disabled (at a high-impedance state) the low impedance of the single enabled output will drive the bus line to a high or low logic le
