Description

General part information

MC74LCX257 Series

The MC74LCX257 is a high performance, quad 2-input multiplexer with 3-state outputs operating from a 2.3 to 3.6V supply. High impedanceTTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VIspecification of 5.5V allows MC74LCX257 inputs to be safely driven from 5.0V 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 (OEbar) input. Current drive capability is 24mA at the outputs.
