DESCRIPTION

The M54/74HC182 is a high speed CMOS FUNC-

TION LOOK AHEAD CARRY GENERATOR

fabricated in silicon gate C²MOS technology. It has

the same high speed performance of LSTTL com-

bined with true CMOS low power consumption.

These circuit are capable of anticipating a carry

across four binary adders or group of adders. They

are cascadable to perform full look-ahead across n-

bit

adders.

Carry,

generate-carry,

and

propagate-carry functions are provided as shown in

the pin connection table. When used in conjunction

with the HC181 arithmetic logic unit, these gener-

ators provide high-speed carry look-ahead

capability for any word length. Each HC182 gener-

ates the look-ahead (anticipated carry) across a

groupoffour ALU’s and, in addition, other carry look-

ahead circuits may be employed to anticipate carry

across sections of four look-ahead packages up to

n-bits. The method of cascading circuits to perform

multi-level look-ahead is illustrated under typical ap-

plication data.

Carry input and output of the ALUs are in their true

form, and the carry propagate (P) and carry gener-

ate (G) are in negated form ; therefore, the carry

functions (inputs, outputs, generate, and propagate)

of the look-ahead generators are implemented in

the compatible forms for direct connection to the

ALU. Reinterpretation of carry functions as ex-

plained onthe HC181 data sheet are alsoapplicable

to and compatible with the look-ahead generator. All

inputs are equipped with protection circuits against

static discharge and transient excess voltage.
