CD40182BMS  
CMOS Look-Ahead Carry Generator  
December 1992  
Features  
Description  
• High Voltage Type (20V Rating)  
The CD40182BMS is a high-speed look-ahead carry gener-  
ator 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, propa-  
gate-carry, and generate-carry functions are provided as  
enumerated in the terminal designation below.  
• Generates High-Speed Carry Across Four Adders or  
Adder Groups  
• High-Speed Operation  
- tPHL, tPLH =100 ns (typ) at VDD = 10V  
The CD40182BMS, when used in conjuction with the  
CD40181BMS arithmetic logic unit (ALU), provides full high-  
speed look-ahead carry capability for up to n-bit words. Each  
CD40182BMS generates the look-ahead (anticipated carry)  
• 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  
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  
• Standardized Symmetrical Output Characteristics  
• Maximum Input Current of 1µA at 18V Over Full Pack- logic, and carry-generate (G) and carry-propagate (P) out-  
age Temperature Range; 100nA at 18V and +25oC  
puts are active-low. Therefore the inputs and outputs of the  
CD40182BMS are compatible.  
• Noise Margin (Over Full Package/Temperature Range)  
- 1V at VDD = 5V  
The CD40182BMS is supplied in these 16-lead outline  
packages:  
- 2V at VDD = 10V  
- 2.5V at VDD = 15V  
Braze Seal DIP  
Frit Seal DIP  
Ceramic Flatpack  
H4V  
H1E  
H6P  
• 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.  
Applications  
• High-Speed Parallel Arithmetric Units  
• Multi-Level Look-Ahead Carry Generation for Long
