This document is about ADM202E/ADM1181A product, it is a RS-232 interface device that complies with the EU directive on EMC (89/336/EEC), and it has ±15 kV ESD protection and supports 230 kbits/s data rate
This datasheet describes the ADM202E and ADM1181A RS‑232 line driver/receiver family. It covers electrical specifications, absolute maximum ratings, pin configuration, functional block diagrams, and circuit operation, including the charge‑pump voltage converter and high‑speed driver and receiver sections. The devices are designed for operation from a single 5 V supply and meet stringent EMC and ESD standards.
Key features include ±15 kV ESD protection on all I/O pins, support for data rates up to 230 kbps, multiple package options (PDIP, wide‑SOIC, narrow‑SOIC, TSSOP), and compliance with the EU EMC directive. The document also provides test results for ESD, EFT, radiated and conducted emissions, as well as mechanical dimensions and ordering information.
