The ADM202E and ADM1181A are high-speed, 2-channel RS-232/V.28 interface devices that operate from a single 5 V power supply. Both products are suitable for operation in harsh electrical environments and are compliant with the EU directive on EMC (89/336/EEC). The products feature low electromagnetic emissions and ESD protection.
The ADM202E and ADM1181A are rugged RS‑232 line‑driver/receiver devices that operate from a single 5 V supply and are designed for harsh electrical environments. They comply with the EU EMC directive and provide extensive protection against electrostatic discharge and fast transients.
Key features include a charge‑pump voltage converter that generates ±10 V from 5 V, high‑speed data transmission up to 230 kbps, low power consumption, and availability in DIP, wide‑SOIC, narrow‑SOIC, and TSSOP packages.
