SN74LS257 数据手册

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

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
