HD74HC257 - Quad. 2-to-1-line Data Selectors/Multiplexers

Datasheet Summary

Description

The large output drive capability coupled with the 3-state feature make this device ideal for interfacing with bus lines in a bus organized system.

When the output control input line is taken high, the outputs of all four multiplexers are sent into a high impedance state.

Features

High Speed Operation: tpd (Data to Y) = 10.5 ns typ (CL = 50 pF).
High Output Current: Fanout of 15 LSTTL Loads.
Wide Operating Voltage: VCC = 2 to 6 V.
Low Input Current: 1 µA max.
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C).

When the output control input line is taken high, the outputs of all four multiplexers are sent into a high impedance state. When the output control line is low, the select input chooses whether the A or B input is used. Features • High Speed Operation: tpd (Data to Y) = 10.
