Replacement verdict
Compatible functional replacement candidate
The ADM232AARN and ADM234LAR-REEL are both dual RS-232 transceivers in a 16-pin SOIC package, making them functionally comparable for many designs. However, the ADM234LAR-REEL operates from a single 3.3 V supply while the ADM232AARN requires a 5 V supply, and their external charge-pump capacitor configurations differ. Designers must verify supply voltage compatibility and review the capacitor requirements before substituting one for the other.
