DESCRIPTION

The M54/74HC182 is a high speed CMOS FUNC­TION LOOK AHEAD CARRY GENERATOR
fabricated insilicongate C2MOStechnology. It has
the same high speed performance of LSTTL com­bined with true CMOS low power consumption.
These circuit are capable of anticipating a carry
acrossfour binary addersor group of adders. They
arecascadable to perform full look-ahead across n­bit adders. Carry, generate-carry, and
propagate-carry functions are providedas shown in
the pinconnection table. When used in conjunction
with the HC181 arithmetic logic unit, these gener­ators provide high-speed carry look-ahead
capability for any word length. Each HC182 gener­ates the look-ahead (anticipated carry) across a
groupoffourALU’sand,inaddition, othercarrylook­aheadcircuits may be employed toanticipate carry
across sections of four look-ahead packages up to
n-bits. Themethod of cascading circuits to perform
multi-levellook-ahead isillustrated under typical ap­plication data.
Carry input and outputof the ALUs are in their true
form, andthe carrypropagate (P) and carrygener­ate (G) are in negated form ; therefore, the carry
functions(inputs, outputs,generate, andpropagate)
of the look-ahead generators are implemented in
the compatible forms for direct connection to the
ALU. Reinterpretation of carry functions as ex­plained ontheHC181datasheetarealsoapplicable
toandcompatible withthelook-aheadgenerator. All
inputs areequipped with protection circuits against
staticdischarge and transient excess voltage.
