GENERAL DESCRIPTION

The ADM3251E is a high speed, 2.5 kV fully isolated, singlechannelRS-232/V.28 transceiver device that operates from asingle 5 V power supply. Due to the high ESD protection on theRIN and TOUT pins, the device is ideally suited for operation inelectrically harsh environments or where RS-232 cables arefrequently being plugged and unplugged.

The ADM3251E incorporates dual-channel digital isolators withisoPower™ integrated, isolated power. There is no requirementto use a separate isolated dc-to-dc converter.

Chip-scale transformeriCoupler® technology from Analog Devices, Inc., is usedboth for the isolation of the logic signals as well as for theintegrated dc-to-dc converter. The result is a total isolation solution.

The ADM3251E conforms to the EIA/TIA-232E and ITU-T V. 28specifications and operates at data rates up to 460 kbps.Four external 0.1 μF charge pump capacitors are used for thevoltage doubler/inverter, permitting operation from a single5 V supply.

The ADM3251E is available in a 20-lead, wide body SOIC packageand is specified over the −40°C to +85°C temperature range.
