Overview
The ADM1181AARWZ is a dual RS-232 transceiver manufactured by Analog Devices Inc. operating from a single 5 V supply with a voltage range of 4.5 V to 5.5 V. It supports data rates up to 230 kbps and features ±15 kV ESD protection on all I/O lines. The device includes two drivers and two receivers, utilizing internal charge pumps to generate required voltages. It operates within an industrial temperature range of -40°C to +85°C and consumes 6 mA at no load. The component is housed in a 16-lead wide SOIC package.
Feature Summary
- Compliant with EU EMC directives for low emissions and high immunity
- Integrated ESD protection rated at ±15 kV air discharge and ±8 kV contact discharge
- Immune to electrical fast transient bursts per IEC1000-4-4 standards
- CMOS technology ensures low power consumption suitable for battery operation
Applications
- General-purpose RS-232 data links
- Portable instruments
- Personal Digital Assistants (PDAs)
Procurement Notes
Verify the specific suffix ARWZ corresponds to the wide SOIC-16 package variant. Confirm that the ordering information matches the manufacturer's current datasheet revision C specifications. Ensure compliance with RoHS requirements as indicated in official documentation before finalizing procurement orders.
Selection Notes
Select this component when robust EMI/EMC performance is required in harsh electrical environments. It serves as a direct pin-compatible upgrade for older MAX202E or LT1181A designs. Verify that the application requires only two channels and operates strictly from a single 5 V power source.
Part Context
This part belongs to the ADM202E/ADM1181A family of RS-232 line drivers and receivers. It is designed to replace legacy components while offering enhanced electromagnetic compatibility. The series provides a solution for applications needing reliable serial communication without external high-voltage supplies.
Replacement Considerations
The ADM1181AARWZ is a pin-compatible replacement for the LTC1181A. It also functions as an upgrade for MAX202E and 232E sockets. Verify pinout compatibility before substituting into existing PCB layouts.
