TRI-STATE® Quad 2-Data Selectors/Multiplexers

General Description\nThese Schottky-clamped high-performance multiplexers feature TRI-STATE outputs that can interface directly with 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 d ● TRI-STATE versions LS157 and LS158 with same pin\n   outs\n● Schottky-clamped for significant improvement in A-C\n   performance\n● Provides bus interface from multiple sources in high\n   performance systems\n● Average propagation delay from data input 12 ns\n● Typical power dissipation\n   LS257;

QUAD 2-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS

QUAD 2-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS The LSTTL/MSI SN54/74LS257B and the SN54/74LS258B 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
