74LCX257

Low Voltage Quad 2-Input Multiplexer

with 5V Tolerant Inputs and Outputs

General Description

The LCX257 is a quad 2-input multiplexer 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 by

placing a logic HIGH on the common Output Enable (OE)

input, allowing the outputs to interface directly with bus-ori-

ented systems.

The 74LCX257 is fabricated with advanced CMOS technol-

ogy to achieve high speed operation while maintaining

CMOS low power dissipation.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Features

Note 1: To ensure the high-impedance state during power up or down, OE

should be tied to V

resistor is determined by the current-sourcing capability of the driver.
