ADM202JRN-REEL

Overview

The ADM202JRN-REEL is a dual-channel RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and supports data transmission rates up to 120 kBaud. The device integrates on-board DC-to-DC converters that generate ±10 V output swings using external 0.1 µF capacitors. It features two drivers and two receivers, with receiver inputs capable of withstanding continuous voltages up to ±30 V. The component is housed in a 16-lead Standard Small Outline Package (SOIC) and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates high-efficiency charge pump circuitry for generating RS-232 voltage levels from a single 5 V supply
• Provides overvoltage protection on receiver inputs to withstand signals exceeding ±30 V
• Includes internal pull-up and pull-down resistors on input pins to manage unused states

Applications

• Computer systems
• Peripherals
• Modems
• Printers
• Instruments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the procurement channel provides valid traceability for the component batch.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with minimal external capacitance. Verify that the application environment remains within the specified 0°C to +70°C operating temperature range. Ensure the system design accommodates the necessary 0.1 µF charge pump capacitors for proper voltage generation.

Part Context

This part belongs to the ADM202 series of high-speed CMOS RS-232 transceivers. The 'J' designation indicates the commercial temperature grade, while 'RN' specifies the narrow-body SOIC package. The '-REEL' suffix denotes the tape-and-reel packaging format intended for automated surface-mount assembly processes.

Replacement Considerations

Direct replacements include other ADM202 variants such as ADM202JRNZ or ADM202JRWZ, provided the package footprint matches the PCB layout. Cross-brand alternatives must be evaluated for pin compatibility and electrical specifications.
