MC74LCX257

Low−Voltage CMOS Quad

2−Input Multiplexer

With 5.0 V−Tolerant Inputs and Outputs

(3−State, Non−Inverting)

MARKING

The MC74LCX257 is a high performance, quad 2−input

multiplexer with 3−state outputs operating from a 2.3 to 3.6 V supply.

High impedance TTL compatible inputs significantly reduce current

loading to input drivers while TTL compatible outputs offer improved

MC74LCX257 inputs to be safely driven from 5.0 V devices.

Four bits of data from two sources can be selected using the Select

input. The four outputs present the selected data in the true

(non−inverted) form. The outputs may be switched to a high

impedance state by placing a logic HIGH on the Output Enable (OE)

input. Current drive capability is 24 mA at the outputs.
