DM74LS257B selectors/multiplexers equivalent, tri-state quad 2-data selectors/multiplexers.
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.
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.
