DESCRIPTION
The HCF4038B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The HCF4038B consists of three serial adder
circuits with common CLOCK and
CARRY-RESET inputs. Each adder has two
provisions for two serial DATA INPUT signals and
an INVERT command signal. When the command
signal is a logical "1", the sum is complemented.
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 negative going clock transition, 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
"0" at the end of each word by applying a logical
"1" signal to a CARRY-RESET input one bit
position before the application of the first bit of the
next word.
