ADM202EARUZ-REEL7

Overview

The ADM202EARUZ-REEL7 is a dual-channel RS-232 transceiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply (4.5 V to 5.5 V) and supports data rates up to 230 kbps. The device features ±15 kV ESD protection on all I/O lines, complying with IEC1000-4-2 standards. It utilizes an internal charge-pump DC-to-DC converter requiring four external 0.1 µF capacitors to generate the necessary voltage levels. The component is housed in a 16-lead TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Compliant with EU EMC directives for low electromagnetic emissions
• Integrated protection against electrostatic discharge and electrical fast transients
• Schmitt-trigger receiver inputs ensure noise immunity
• Internal pull-down resistors maintain defined logic states

Applications

• General-purpose RS-232 data links
• Portable instruments
• Personal Digital Assistants (PDAs)

Procurement Notes

Verify the specific ordering suffix RUZ corresponds to the TSSOP-16 package configuration. Confirm that the REEL7 designation indicates tape and reel packaging rather than tube packaging. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity before integration.

Selection Notes

Select this component when robust EMI/EMC performance is required in harsh electrical environments. It serves as a direct upgrade for legacy MAX202E or ADM202E designs. Choose this model if space constraints favor the compact TSSOP package over larger SOIC or PDIP options. Ensure the application requires full-duplex communication at speeds up to 230 kbps.

Part Context

This device belongs to the ADM202E family, which provides enhanced reliability compared to earlier generations. It is functionally compatible with standard RS-232 interfaces while offering superior transient protection. The ADM202E series is designed to replace older transceivers without requiring significant circuit redesigns.

Replacement Considerations

The ADM202E is a pin-compatible replacement for the MAX202E and LT1181A. Verify that substitute components support the same 230 kbps data rate and ±15 kV ESD protection levels.
