ADM202JRNZ-REEL7

Overview

The ADM202JRNZ-REEL7 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 utilizes an internal charge pump to generate ±10 V output levels, meeting TIA/EIA-232-E specifications. The device supports data rates up to 120 kB with a typical quiescent current of 2.5 mA. It features Schmitt-triggered receivers with hysteresis for noise immunity and overvoltage protection on inputs up to ±30 V. Packaged in a 16-lead narrow SOIC (R-16), it requires external 0.1 µF capacitors for the voltage converter.

Feature Summary

• Integrates high-efficiency on-chip dc-to-dc converters requiring only small 0.1 µF external capacitors
• Provides full compliance with TIA/EIA-232-E and V.28 interface standards
• Includes built-in ESD protection exceeding 2 kV and receiver input overvoltage tolerance up to ±30 V

Applications

• Computer serial communication ports
• Peripheral equipment interconnects
• Modem signal processing
• Printer interface circuits
• Industrial instrumentation control

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status indicated by the 'Z' suffix in the part number. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering. Validate package integrity against shipping damage risks associated with reel packaging formats.

Selection Notes

Select this component when designing systems requiring low-power RS-232 connectivity powered exclusively by a 5 V rail. The narrow SOIC package suits space-constrained printed circuit board layouts. Consider the specific thermal dissipation limits of the R-16 package option during high-load operational scenarios.

Part Context

This part belongs to the ADM202 series of CMOS RS-232 transceivers. The 'J' designation indicates commercial temperature range operation from 0°C to 70°C. The 'RN' specifies the 16-lead narrow SOIC physical footprint, while 'Z' confirms lead-free manufacturing compliance.

Replacement Considerations

ADM202JRNZ serves as the tube-pack equivalent of this reel-part. Other ADM202 variants offer different packages such as wide SOIC or PDIP.
