General Description
These circuits are high-speed, look-ahead carry generators, capable of anticipating a carry across four binary adders or groups of adders. They are cascadable to perform full look-ahead across n-bit adders. Carry, generatecarry, and propagate-carry functions are provided as shown in the pin designation table.

Features
■ Typical propagation delay time 7 ns
■ Typical power dissipation 260 mW
