Low-Voltage CMOS Quad
2-Input Multiplexer
With 5 V−Tolerant Inputs
(Non−Inverting)
MC74LCX157A
www.onsemi.com
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

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.
