Overview
The ADM202EARU-REEL 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 voltage converter requiring four external 0.1 µF capacitors. The component is housed in a 16-lead TSSOP package and functions as a robust upgrade for legacy MAX202E/MAX232E interfaces.
Feature Summary
- Compliant with EU EMC directive 89/336/EEC for low emissions and high immunity
- Integrated ESD protection rated at ±15 kV air-gap and ±8 kV contact discharge
- Internal charge-pump eliminates need for external negative voltage supplies
- Schmitt-trigger receivers provide noise immunity and error-free reception
Applications
- General-purpose RS-232 data links
- Portable instruments and handheld devices
- Personal Digital Assistants (PDAs)
Procurement Notes
Verify the specific ordering suffix RU-REEL against the manufacturer's current datasheet to confirm the tape-and-reel packaging format and lead-free status. Ensure compatibility with existing PCB footprints designed for standard TSSOP-16 components before finalizing procurement orders.
Selection Notes
Select this component when upgrading from older MAX202E or ADM232L designs requiring enhanced EMI/EMC performance. It is suitable for applications needing full-duplex communication at speeds up to 230 kbps without external negative voltage generation. Verify that the system environment requires industrial temperature range operation (-40°C to +85°C).
Part Context
This part belongs to the ADM202E family of RS-232 line drivers and receivers. It serves as a pin-compatible replacement for legacy interface chips like the MAX202E and LT1181A. The device integrates CMOS technology to minimize power dissipation while maintaining high transmission rates and robust transient protection capabilities.
Replacement Considerations
Publicly confirmed substitutes include ADM202EARNZ and ADM202EARWZ. These variants offer identical electrical specifications but differ in package type (SOIC-16 vs. TSSOP-16). Verify mechanical footprint compatibility before substitution.
