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

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 +25^oC

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

• 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.
