MC74LCX157 Datasheet | Motorola Semiconductor

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low-Voltage CMOS Quad 2-Input Multiplexer With 5V-Tolerant Inputs (Non-Inverting) The MC74LCX157 is a high performance, quad 2- input multiplexer operating from a 2.7 to 3.6V supply. High impedance TTL patible inputs significantly reduce current loading to input drivers while TTL patible outputs offer improved switching noise performance. A VI specification of 5.5V allows MC74LCX157 inputs to be safely driven from 5V 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 MC74LCX157 can also be used as a function generator. Current drive capability is 24m A at the outputs.
