DESCRIPTION
The
HCC/4032B/4038B
(extended temperature
range) and
HCF4032B/4038B
(intermediate tem-
perature range) are monolithic integrated circuits,
available in 16-lead dual in-line plastic or ceramic
package and plastic micro package.
The
HCC/HCF4032B
and
HCC/HCF4038B
types
consist of three serial adder circuits with common
CLOCK and CARRY-RESET inputs. Each adder
has two provisions for two serial DATA INPUT sig-
nals and an INVERT command signal. When the
command signal is a logical 鈥?鈥? the sum is com-
plemented. Data words enter the adder with the
least significant bit first ; the sign bit trails. The output
is the MOD 2 sum of the input bits plus the carry from
the previous bit position. The carry is only added at
the positive-going clock transition for the
HCC/HCF4032B
or at the negative-going clock for
the
HCC/HCF4038B,
thus, for spike-free operation
the input data transitions should occur as soon as
possible after the triggering edge. The CARRY is
reset to a logical 鈥?鈥?at the end of each word by ap-
plying a logical 鈥?鈥?signal to a CARRY-RESET input
one-bit-position before the application of the first bit
of the next word.
