54LS258B MULTIPLEXER Datasheet, Distribuidor, stock y mejor precio

Part Number	54LS258B
Manufacturer	National Semiconductor
Title	Quad 2-Data Selectors/Multiplexers
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 single enabled output will drive the bus line to a .
Features	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 Alternate military aerospace devices (54LS257A 54LS258A) are available Contact a National Semicondu.
