|
|
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 |
|
LOW±VOLTAGE CMOS |
|
impedance TTL compatible inputs significantly reduce current loading to |
|
||
input drivers while TTL compatible outputs offer improved switching noise |
QUAD 2±INPUT MULTIPLEXER |
||
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 |
|
D SUFFIX |
|
HIGH on the Output Enable (OE) input. Current drive capability is 24mA |
|

|
PLASTIC SOIC |
||
at the outputs. |
