The NTE74182 is a high−speed, look−ahead carry generator in a 16−Lead plastic DIP type package capable of anticipating a carry across four binary adders or group of adders. It is capable or performing full look−ahead across n−bit adders. Carry, generate−carry, and propagate−carry functions are provided as enumerated in the pin designation table. When used in conjunction with the NTE74181, NTE74LS181, or NTE74S181 arithmetic logic unit (ALU), this generator provides high−speed carry look−ahead capability for any word length. This device generates look−ahead (anticipated carry) across a group of four ALU’s and, in addition, other carry look− ahead circuits may be employed to anticipate carry across sections of four look−ahead packages up to n−bits.
