Low-Voltage CMOS Quad 2-Input Multiplexer

Active

Overview

The MC74LCX157A is a high performance, quad 2−input multiplexer operating from a 1.65 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input  drivers while TTL compatible outputs offer improved switching noise performance. A VI  specification of 5.5 V allows MC74LCX157A inputs to be safely driven from 5 V devices.
Four bits of data from two sources can be selected using the Select and Enable inputs. The four outputs present the selected data in the true (non−inverted) form. The MC74LCX157A can also be used as a function generator. Current drive capability is 24 mA at the outputs.

  • Applications requiring 1.65 to 3.6 V VCC Operation

  • VIH at 1.8V bus in Telecom market

  • Designed for 1.65 to 3.6 V VCC Operation
