描述 Description
QUAD 2-INPUT MULTIPLEXER WITH 3-STATE OUTPUTSTheLSTTL/MSI SN54/74LS257B and the SN54/74LS258B are Quad 2-InputMultiplexers with 3-state outputs. Four bits of data from twosources canbe selected using a Common Data Select input. The four outputs present the selected data in true (non-inverted) form. The outputs may be switched to ahigh impedance state with a HIGH on the common Output Enable (EO) In put,allowing the outputs to interface directly with bus oriented systems. It is fabricatedwith the Schottky barrier diode process for high speedand is completely compatible with all Motorola TTL families.
? Schottky Process For High Speed
? Multiplexer Expansion By Tying Outputs Together
? Non-Inverting 3-State Outputs
? Input Clamp Diodes Limit High Speed Termination Effects
? Special Circuitry Ensures Glitch Free Multiplexing
? ESD 3500 Volts
