SEMICONDUCTOR TECHNICAL DATA

L SUFFIX

CERAMIC

CASE 620

The MC14582B is a CMOS look–ahead carry generator capable of

anticipating a carry across four binary adders or groups of adders. The

device is cascadable to perform full look–ahead across n–bit adders. Carry,

generate–carry, and propagate–carry functions are provided as enumerated

in the pin designation table shown below.
