ADM202JRN-REEL7

Overview

The ADM202JRN-REEL7 is a dual-channel RS-232 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 supply current of 2.5 mA. It features overvoltage protection on receiver inputs up to ±30 V and includes ESD protection exceeding 2 kV. Packaged in a 16-lead SOIC (R-16), it functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrates on-chip dc-to-dc converters allowing operation with small 0.1 µF external capacitors.
• Provides full compliance with TIA/EIA-232-E and V.28 interface standards.
• Includes Schmitt trigger receivers with hysteresis for noise immunity.
• Features TTL/CMOS compatible inputs with internal pull-up resistors.

Applications

• Computer serial port interfaces
• Peripheral equipment connections
• Modem communication links
• Printer interface circuits
• Industrial instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and RoHS compliance status. Confirm that the component meets the required environmental operating conditions for the intended application before procurement.

Selection Notes

Select this component when a single 5 V supply is available and RS-232 signaling is required without external voltage inverters. Ensure the design accommodates the necessary external 0.1 µF capacitors for the charge pump circuit. Verify that the 120 kB baud rate capability aligns with system timing requirements.

Part Context

This part belongs to the ADM202 series of high-speed RS-232 transceivers. It is designed as a drop-in replacement for legacy drivers while offering lower power consumption through BiCMOS technology. The J variant indicates a commercial temperature rating suitable for general-purpose electronic equipment.

Replacement Considerations

ADM202JRNZ-REEL7 is a verified RoHS-compliant substitute within the same package configuration.
