ADM211ARZ - 5V 4/5 RS-232 Transceiver | Analog Devices
MPN: ADM211ARZ ✓ NakahandaADM211ARZ Ulas
An RS-232 transceiver is an interface IC that combines differential line drivers and receivers for serial data transmission over single-ended, bipolar signaling connections. The driver converts CMOS logic levels into RS-232 voltage levels, while the receiver converts incoming RS-232 signals back into CMOS-compatible logic. Within the interface hierarchy, the ADM211ARZ belongs to the RS-232 transceiver class, interface IC category, and broader integrated-circuit family.
The ADM211ARZ provides four transmit channels and five receive channels in one package. Its 200 kbps maximum signaling rate supports moderately high-speed equipment links, while the integrated on-board DC-to-DC converters generate the bipolar voltage levels required by RS-232 from a single 5 V supply. The 0.1 µF charge-pump capacitor requirement reduces the number of external support components compared with discrete level-shifting designs.
The ADM211 family is specified for a 4.5 V to 5.5 V supply range, with an on-board converter capable of producing approximately ±9 V output swing from the 5 V supply. This architecture allows operation without external ±12 V rails. The device is identified as a low-power RS-232 solution and is suited to portable, industrial-control, instrumentation, and embedded equipment interfaces where supply constraints and channel count are important.
Typical uses include multi-channel serial-port connections, industrial data-acquisition equipment, test and measurement systems, and embedded control systems. A four-driver configuration can support four outbound channels, while the fifth receiver can monitor an additional incoming signal. This asymmetry is useful in systems where one node transmits on several lines but receives status, acknowledgment, or data from one additional line.
PCB design should preserve short return paths for the RS-232 cable-side pins and provide an uninterrupted ground reference. Place the 0.1 µF charge-pump capacitor close to the device and follow the datasheet connection diagram. RS-232 interfaces also require careful segregation between cable-side and logic-side nets to avoid electrostatic-discharge events propagating into surrounding circuitry.
This product page combines the manufacturer device information with package, application, pricing workflow, replacement, and design guidance. It also distinguishes a true same-footprint replacement from alternatives that require a different package or a different channel configuration, helping engineers make a board-level selection without relying on a generic substitute list.

ADM211ARZ ay nararapat para sa 6 aplikasyons: Industrial Serial Data Acquisition, Test and Measurement Equipment, Embedded Control and Service Interfaces, Point-of-Sale and Peripheral Equipment, Instrumentation and Control Panels, Portable and Service Equipment.
Industrial Serial Data Acquisition
The ADM211ARZ fits multichannel industrial data-acquisition equipment that must communicate over RS-232 without external ±12 V rails. Its four drivers can carry commands or configuration data to several field instruments, while five receivers can monitor responses, acknowledgments, and status signals. The 200 kbps data rate is suitable for moderate-speed supervisory links, and the single 4.5 V to 5.5 V supply simplifies system power distribution. Keep the 0.1 µF charge-pump capacitor close to the device and provide a solid ground reference between the logic system and connected equipment.
Inirekomenda
Test and Measurement Equipment
The ADM211ARZ is appropriate for instruments that expose several RS-232 ports for remote control and result reporting. Four transmit channels can address separate controllers, and five receive channels provide additional channels for trigger, ready, error, or measurement-status information. Its 200 kbps maximum rate supports moderate-speed command traffic, while the integrated converter produces approximately ±9 V from a 5 V supply. Place the charge-pump capacitor according to the manufacturer layout and keep sensitive measurement circuitry away from cable-side connector and driver return paths.
Inirekomenda
Embedded Control and Service Interfaces
The ADM211ARZ supports embedded equipment that needs more than one legacy serial connection but has only a 5 V power rail. Four drivers can interface with service connectors, printers, controllers, or external adapters, while five receivers can accept data from multiple sources. Its 200 kbps rate is appropriate for configuration and diagnostic traffic rather than continuous bulk transfer. Maintain a common ground with connected RS-232 equipment, route cable-side traces away from precision logic, and verify connector protection because transients on external cables can propagate into the transceiver pins.
Inirekomenda
Point-of-Sale and Peripheral Equipment
The ADM211ARZ can connect a compact controller or peripheral system to multiple RS-232 accessories from a single 5 V supply. Four drivers suit devices such as scales, printers, scanners, or receipt peripherals, while the five receivers provide room for device acknowledgments and independent status lines. The 200 kbps operating rate is sufficient for short transactions and configuration exchanges. Confirm the logic levels and handshake requirements of each connected peripheral, and use a continuous ground conductor in the RS-232 cable to provide a stable reference.
Inirekomenda
Instrumentation and Control Panels
The ADM211ARZ is well suited to instrumentation panels where several control commands and feedback signals use RS-232. Its four transmit channels can drive separate setpoints or instrument commands, while five receivers can return process values, alarms, and acknowledgments. Operating from 4.5 V to 5.5 V allows integration with conventional 5 V control electronics, and the approximately ±9 V generated swing provides RS-232-compatible cable-side levels. Follow the manufacturer's charge-pump layout, preserve short ground returns, and place input protection near exposed connectors.
Inirekomenda
Portable and Service Equipment
The ADM211ARZ supports portable service equipment and field-service interfaces where a single 5 V rail is more practical than external ±12 V power. The four drivers can serve diagnostic, programming, or communication channels, and the five receivers can collect equipment responses and remote-status signals. Its 200 kbps rate suits supervisory traffic, while the integrated converter reduces the external power-tree burden. Validate the complete cable assembly, maintain equipment grounding, and provide appropriate transient protection because service ports are often exposed to electrostatic discharge and cable transients.

Talaan ng Disenyo
Place the 0.1 µF charge-pump capacitor directly between the designated capacitor pins and follow the Analog Devices ADM211 Data Sheet (Rev. D) layout. Keep the loop formed by the capacitor, its return path, and the device pins as short as practical. Correct capacitor polarity and connection are critical because reversing or relocating the component can impair power-converter startup and introduce additional switching transients into the interface.
Separate cable-side driver and receiver traces from sensitive logic and analog nets. RS-232 driver outputs use high voltage swings and switching edges, so route them away from clocks, precision references, and low-level sensor inputs. Connect the logic ground and cable ground with a short, deliberate return path, and avoid allowing cable-side return currents to pass through sensitive ground regions of the board.
Do not treat any 28-pin RS-232 transceiver as interchangeable solely because the package matches. Before replacing the ADM211ARZ with the ADM211AR or LT1136ACSW#PBF, verify supply range, shutdown behavior, receiver enable logic, data rate, charge-pump capacitor value, and pin-level timing. The ADM211AR ordering format must also match the assembly process, and all exposed cable connections require suitable transient protection.
Keep the RS-232 connector interface and transceiver output routing away from precision analog sections, and provide a continuous ground conductor in the cable where the application permits it. Although the ADM211ARZ generates approximately ±9 V swing from a 5 V supply, the driver transitions can still produce radiated noise. Use the shortest practical driver traces, avoid broad test pads on cable-side nets, and evaluate enclosure or board-level filtering when the interface is adjacent to sensitive measurements.
Impormasyon ng Pagsunod sa Kautusan
The manufacturer product information confirms EIA-232-E and V.28 compatibility but does not explicitly state the requested environmental or automotive compliance statuses. AEC-Q100 is treated as not applicable because this is a general-purpose RS-232 interface IC rather than an automotive-qualified device.
