Low-Voltage CMOS Quad
2-Input Multiplexer
With 5V-Tolerant Inputs and Outputs
(3-State, Inverting)
The MC74LCX258 is a high performance, quad 2–input inverting
multiplexer with 3–state outputs operating from a 2.7 to 3.6V 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 5.5V allows MC74LCX258 inputs to be
safely driven from 5V devices.
Four bits of data from two sources can be selected using the Select
input. The four outputs present the selected data in the inverted form. The
outputs may be switched to a high impedance state by placing a logic
HIGH on the Output Enable (OE) input. Current drive capability is 24mA
at the outputs.
