QUAD 2-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS

The LSTTL/MSI SN54/74LS257B and the SN54/74LS258B are Quad 2-Input Multiplexers with 3-state outputs. Four bits of data from two sources can be 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 a high impedance state with a HIGH on the common Output Enable (EO) Input, allowing the outputs to interface directly with bus oriented systems. It is fabricated with the Schottky barrier diode process for high speed and is com pletely 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
