CD4008BM - 4-Bit Full Adder

Datasheet Summary

Description

The CD4008B types consist of four full-adder stages with fast look-ahead carry provision from stage to stage Circuitry is included to provide a fast ‘‘parallel-carry-out’’ bit to permit high-speed operation in arithmetic sections using several CD4008B’s CD4008B inputs include the four sets of bits t
