CD40182BMS Datasheet | Intersil

December 1992 CMOS Look-Ahead Carry Generator Description 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...
