LOW POWER SCHOTTKY
-----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 ON Semiconductor 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
