74LS257 - Quad 2-Input Multiplexer with 3-State Outputs
The LSTTL/MSI SN74LS257B and the SN74LS258B 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 completely compatible with all 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
