74LS258B Datasheet and Specifications PDF

These 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 .

Y TRI-STATE versions LS157 and LS158 with same pinouts Y Schottky-clamped for significant improvement in A-C performance Y Provides bus interface from multiple sources in highperformance systems Y Average propagation delay from data input 12 ns Y Typical power dissipation LS257B 50 mW LS258B 35 mW Y.

The LS257B and LS258B are Quad 2-Input Multiplexers with 3-state outputs. They select four bits of data from two sources each under control of a Common Data Select Input. When the Select Input is LOW,.
