SEMICONDUCTOR TECHNICAL DATA
MC14582B
Look-Ahead Carry Block
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.
Expandable to any Number of Bits
All Buffered Outputs
