Overview
The ADM232AARW-REEL is a high-speed RS-232 line driver and receiver manufactured by Analog Devices Inc. It operates from a single 5 V power supply and supports transmission rates up to 200 kB/s. The device integrates two drivers and two receivers within a 16-lead wide body SOIC package (RW-16). Internal charge pumps generate the required bipolar voltages using four external 0.1 µF capacitors. It meets EIA-232-E and V.28 specifications, features ±9 V output swing with a 5 V supply, and includes internal pull-up resistors on TTL/CMOS inputs.
Feature Summary
- Integrates an on-board DC-DC converter that generates bipolar voltage levels from a single 5 V supply using small external capacitors.
- Provides full duplex communication capability with two independent drivers and two independent receivers.
- Includes internal protection mechanisms such as Schmitt trigger inputs for noise immunity and overvoltage tolerance on receiver pins.
Applications
- Computers
- Peripherals
- Modems
- Printers
- Instruments
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and reel configuration. Ensure the component matches the required industrial temperature range and RoHS compliance status before integration into production designs.
Selection Notes
Select this component when a pin-compatible upgrade for legacy MAX232 or AD232 designs is required. It is suitable for applications needing high-speed data transfer up to 200 kB/s without requiring negative voltage rails. Verify that the system design accommodates the necessary external 0.1 µF capacitors for the charge pump circuitry.
Part Context
This part belongs to the ADM222/ADM232A/ADM242 family of CMOS RS-232 transceivers. While sharing similar core functionality, the ADM232A differs from the ADM222 and ADM242 by lacking dedicated shutdown and enable control pins. It serves as a direct replacement for older generation devices in standard serial communication interfaces.
Replacement Considerations
Publicly confirmed substitutes include ADM232AARNZ and ADM232AARWZ. These variants share identical electrical characteristics but differ in packaging options or lead-free compliance status.
