74LS257B Datasheet

Features and benefits

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.

Description

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 a high impedance state) the low impedance of the s.
