GENERAL DESCRIPTION  
The ADM3251E conforms to the EIA/TIA-232E and ITU-T V. 28  
specifications and operates at data rates up to 460 kbps.  
The ADM3251E is a high speed, 2.5 kV fully isolated, single-  
channel RS-232/V.28 transceiver device that operates from a  
single 5 V power supply. Due to the high ESD protection on the  
Four external 0.1 μF charge pump capacitors are used for the  
voltage doubler/inverter, permitting operation from a single  
5 V supply.  
RIN and TOUT pins, the device is ideally suited for operation in  
electrically harsh environments or where RS-232 cables are  
frequently being plugged and unplugged.  
The ADM3251E is available in a 20-lead, wide body SOIC package  
and is specified over the −40°C to +85°C temperature range.  
The ADM3251E incorporates dual-channel digital isolators with  
isoPower™ integrated, isolated power. There is no requirement  
to use a separate isolated dc-to-dc converter. Chip-scale trans-  
former iCoupler® technology from Analog Devices, Inc., is used  
both for the isolation of the logic signals as well as for the  
integrated dc-to-dc converter. The result is a total isolation  
solution.
