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.
