The ADM1181AARWZ-REEL is a high speed 2-channel RS-232/V.28 Line Driver/Receiver operates from a single 5V power supply. The interface device is suitable for operation in harsh electrical environments and is compliant with the EU directive on EMC. Both the level of electromagnetic emissions and immunity are in compliance. EM immunity includes ESD protection in excess of ±15kV on all I/O lines, fast transient/burst protection and radiated immunity. Four external 0.1μF charge-pump capacitors are used for the voltage doubler/inverter, permitting operation from a single 5V supply. The ADM1181A provides a robust pin-compatible upgrade for the LTC1181A.
