MC74LCX158 Low-Voltage CMOS Quad 2-Input Multiplexer With 5 V−Tolerant Inputs (Inverting) The MC74LCX158 is a high performance, quad 2−input inverting multiplexer 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 switching noise performance. A VI specification of 5.5 V allows MC74LCX158 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 inverted form. The MC74LCX158 can also be used as a function generator. Current drive capability is 24 mA at the outputs. Features  Designed for 2.3 to 3.
