The CD40182BMS is a high-speed look-ahead carry generator capable of anticipating a carry across four binary adders or groups of adders. The CD40182BMS is cascadable to perform full look-ahead across n-bit adders. Carry, propagate- carry, and generate-carry functions are provided as enumerated in the terminal designation below.

The CD40182BMS, when used in conjuction with the CD40181BMS arithmetic logic unit (ALU), provides full highspeed look-ahead carry capability for up to n-bit words. Each CD40182BMS generates the look-ahead (anticipated carry) across a group of four ALU's. In addition, other CD40182BMS's may be employed to anticipate the carry across sections of four look-ahead blocks up to n-bits. Carry inputs and outputs of the CD40181BMS are active-high logic, and carry-generate (G) and carry-propagate (P) outputs are active-low. Therefore the inputs and outputs of the CD40182BMS are compatible.

The CD40182BMS is supplied in these 16-lead outline
     packages:Braze Seal DIP            H4V
     Frit Seal DIP                                H1E
