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

LOW POWER SCHOTTKY

Quad 2-Input Multiplexer with 3-State Outputs The LSTTL/MSI SN74LS257B and the SN74LS258B are Quad 2-Input Multiplexers with 3-state outputs. Four bits of data from two sources can be selected using a Common Data Select input. The four outputs present the selected data in true (non-inverted)
