ADM213AR Übersicht
An RS-232 transceiver is an interface IC that converts logic-level TTL or CMOS signals into RS-232-compatible differential voltage levels, while converting received RS-232 levels back into logic-level signals. The ADM213AR belongs to the line-driver/receiver and interface-IC hierarchy used for EIA-232-E and V.28 communications where ±12 V is unavailable. Integrating charge-pump converters eliminates the need for a separate negative supply in many point-to-point interfaces.
Key features include four RS-232 drivers, five receivers, two receivers active in shutdown, 0.1 µF charge-pump capacitors, 120 kbps data-rate support in the cited feature data, and approximately ±9 V output swing with a 5 V supply. The reported low-power figure is 15 mW. The 28-SOIC package is suitable for conventional through-hole PCB assembly, and the device is identified as a plug-in upgrade for MAX205, MAX211, and MAX213 families.
The device uses a single positive supply, making it useful for systems that cannot easily provide negative RS-232 rails. Its receiver inputs are specified for ±30 V input levels, while latch-up protection is listed as a feature. The shutdown function can reduce system power when the interface is inactive, although two receivers remain operational for selected monitoring or wake-up signals.
Typical applications include industrial RS-232 links, instrumentation, point-of-sale equipment, data acquisition systems, embedded serial ports, and legacy computer peripherals. When using the device, verify the exact pinout, shutdown polarity, receiver enable behavior, charge-pump capacitor values, and RS-232 signal polarity against the manufacturer datasheet before final PCB release.

Typische Anwendungen
ADM213AR ist geeignet für 6 Anwendungs: Industrial RS-232 Communication Port, Point-of-Sale Terminal Interface, Data Acquisition and Instrumentation, Embedded Serial Port Expansion, Legacy Computer Peripheral Connection, Low-Power Shutdown Interface.
Industrial RS-232 Communication Port
The ADM213AR fits industrial serial ports that use a single +5 V supply and require four transmit channels, five receive channels, and low-power shutdown behavior. Its integrated converters provide approximately ±9 V swing, avoiding the need for a separate negative rail. Place the receiver and driver lines through the appropriate protection and grounding network, and verify the 28-SOIC pinout before layout release. The device's stated 120 kbps or 200 kbps capability must be reconciled against the exact datasheet revision and system cable length.
Empfohlen
Point-of-Sale Terminal Interface
The ADM213AR can support legacy point-of-sale peripherals that expose RS-232 through a +5 V system without a negative power rail. Its four drivers and five receivers provide several channels for receipt printer, display, scanner, or service-port connections, while shutdown helps reduce consumption when the terminal is idle. Validate signal polarity, cable length, grounding, and surge exposure at the connector because those system-level requirements are not specified by the component alone.
Empfohlen
Data Acquisition and Instrumentation
The ADM213AR is suitable for legacy laboratory and industrial instrumentation that uses RS-232 control or measurement links. The onboard charge pumps remove the need for a separate negative supply, while the receiver input rating of ±30 V can improve tolerance to external line transients. The design should still include connector-side protection, controlled grounding, and isolation where required. Use the receiver outputs and enable pins in accordance with the manufacturer timing and polarity data.
Empfohlen
Embedded Serial Port Expansion
The ADM213AR can add multiple RS-232 channels to an embedded controller or industrial computer that already generates a clean 5 V rail. Four drivers support outbound control or status signals, and five receivers support inbound device responses or monitoring lines. The component is particularly useful for legacy equipment that cannot use a modern USB or Ethernet interface. Firmware must account for shutdown polarity, enable timing, and any receiver channels that remain active during shutdown.
Empfohlen
Legacy Computer Peripheral Connection
The ADM213AR is appropriate for connecting legacy printers, scales, programmers, and service equipment to modern +5 V controller boards. Its integrated DC-to-DC converters generate the required RS-232 levels from one positive supply, simplifying systems without a negative rail. The interface still requires careful common-ground design and protection at the external connector. Confirm that the cable is wired for the device's true RS-232 polarity rather than assuming an RS-232 label guarantees compatibility.
Empfohlen
Low-Power Shutdown Interface
The ADM213AR supports systems that need to reduce power while retaining selected receive monitoring paths. Its shutdown and enable pins are explicitly listed, and the supplied product information states that two receivers remain active during shutdown. This arrangement can allow a controller to detect a limited remote signal without keeping every driver active. The exact active-channel states and timing must be taken from the manufacturer datasheet, and the power budget should include external pull-up or pull-down networks.

- Four-driver, five-receiver organization (vs. MAX211CAI+)
Designhinweise
Place the 0.1 µF charge-pump capacitors close to the pins identified in the current Analog Devices datasheet. Keep the charge-pump loop compact and route the associated current paths away from sensitive receiver inputs. The supplied data confirms 0.1 µF capacitors but does not provide a complete PCB layout, so follow the manufacturer recommended land pattern and placement sequence.
Do not treat every RS-232 driver/receiver IC with a 28-SOIC outline as automatically interchangeable. Verify pin numbering, shutdown polarity, enable polarity, receiver output states, charge-pump capacitor pins, and supply sequencing against the exact replacement datasheet. The supplied data calls ADM213AR a plug-in upgrade for MAX205, MAX211, and MAX213 families, but it does not provide a complete pin-by-pin equivalence matrix.
Keep external RS-232 connector protection, chassis or signal ground, and transceiver routing in the design review. The device can operate from one +5 V rail and produces approximately ±9 V internally, but cable transients and ground offsets are system-level hazards. Confirm connector creepage, ESD protection, and the receiver's ±30 V input rating against the actual enclosure and cabling environment.
Compliance-Informationen
The retrieved comparison data reports RoHS-related information, while definitive REACH, lead-free, halogen-free, and conflict-minerals status were not supplied. Verify current manufacturer or distributor documentation before making a compliance claim.
