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 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 patible. The CD40182BMS is supplied in these 16-lead outline packages: Braze Seal DIP Frit Seal DIP Ceramic Flatpack H4V H1E H6P Features - High Voltage Type (20V Rating) - Generates High-Speed Carry Across Four Adders or Adder Groups - High-Speed Operation - t PHL, t PLH =100 ns (typ) at VDD = 10V - Cascadable for Fast Carries Over N Bits - Designed for Use with CD40181BMS ALU - 100% Tested for Quiescent Current at 20V - 5V, 10V and 15V Parametric Ratings - Standardized Symmetrical Output Characteristics - Maximum Input Current of 1µA at 18V Over Full Package Temperature Range; 100n A at 18V and +25o C - Noise Margin (Over Full Package/Temperature Range) - 1V at VDD = 5V - 2V at VDD = 10V - 2.5V at VDD = 15V - Meets All Requirements of JEDEC Tentative Standard No. 13B, “Standard Specifications for Description of ‘B’ Series CMOS Devices” The CD40182BMS is similar to industry type MC14582.
