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

(with noninverted 3-state outputs)

REJ03D0601–0200

(Previous ADE-205-478)

Rev.2.00

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. When the output control line is low, the select input chooses whether the A or B input is

used.

Features

•

High Speed Operation: t_pd(Data to Y) = 10.5 ns typ (C_L= 50 pF)

High Output Current: Fanout of 15 LSTTL Loads

Wide Operating Voltage: V_CC= 2 to 6 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 4 µA max (Ta = 25°C)
