Description: 3-STATE Quad 2-Data Selectors/Multiplexers
s 3-STATE versions LS157 and LS158 with same pinouts s Schottky-clamped for significant improvement in A-C
performance s Provides bus interface from multiple sources in
h.
These Schottky-clamped high-performance multiplexers feature 3-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.
