ADM3202ARUZ-REEL7

Drivers, Receivers, Transceivers Overview

The ADM3202ARUZ-REEL7 is a low-power, dual-channel RS-232 transceiver manufactured by Analog Devices Inc. It operates from a single 3.3 V power supply with a range of 3.0 V to 5.5 V and supports data rates up to 460 kbps. The device features two drivers and two receivers in full-duplex mode, utilizing an internal charge pump that requires four external 0.1 μF capacitors. It is housed in a 16-lead TSSOP package (RU-16) and functions within an industrial temperature range of -40°C to +85°C. The component includes ESD protection on RS-232 pins rated at ±8 kV contact discharge and ±15 kV air gap discharge.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump voltage converter generates required positive and negative supplies from a single 3.3 V input using only four small external capacitors.
• Provides robust ESD protection on all RS-232 interface pins to withstand electrostatic discharge events common in portable environments.
• CMOS technology ensures minimal power dissipation, making the device suitable for battery-powered applications without requiring a shutdown pin.

Drivers, Receivers, Transceivers Applications

• General-purpose RS-232 data links
• Portable instruments
• Printers and palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the RU-16 package designation and REEL7 suffix against official Analog Devices documentation to confirm the specific tape-and-reel packaging format. Ensure the ordering part number matches the exact industrial temperature grade and RoHS compliance status required for the target assembly process.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is needed with high-speed transmission capabilities up to 460 kbps. It serves as a direct upgrade for legacy MAX3222 or LTC1385 designs, offering improved performance while maintaining compatibility with standard 3.3 V logic systems.

Drivers, Receivers, Transceivers Part Context

This device belongs to the ADM3202/ADM3222/ADM1385 family of line drivers and receivers. It is designed as an enhancement to the earlier AD230 to AD241 series, providing plug-in compatibility with materially different application requirements while supporting modern low-voltage CMOS logic standards.

Drivers, Receivers, Transceivers Replacement Considerations

The ADM3202ANZ and ADM3202ARNZ are confirmed pin-compatible replacements within the same family, differing primarily in PDIP and SOIC_N package options respectively. Verify that the alternative package maintains the required thermal and mechanical constraints for the PCB layout.
