ADM206ARZ - 4/3 RS-232 Transceiver, 200 kbps | Analog Devices
MPN: ADM206ARZ ✓ NakahandaADM206ARZ Ulas
An RS-232 transceiver is an interface IC that converts digital logic-level signals into RS-232 line levels and receives RS-232 signals for conversion back to CMOS logic levels. Within the interface hierarchy, the ADM206ARZ belongs to the RS-232 transceiver class of communication interface ICs. It supports point-to-point serial links where ground and signal conductors connect two pieces of equipment over distances defined by the RS-232 electrical standard.
The device provides four line drivers, three receivers, a shutdown pin, and an enable pin. Its advertised 200 kbps maximum data rate suits moderate-speed data acquisition, industrial control, instrumentation, and equipment interfaces. The ±9 V charge-pump outputs provide greater noise margin than a simple ground-referenced driver would offer, while the low-power design is rated at 15 mW under the stated operating condition.
The 0.1 µF external charge-pump capacitor requirement simplifies external power-supply design compared with discrete RS-232 level-shifter networks. A single 5 V rail powers the receiver, driver, and charge-pump circuitry, reducing board area and assembly complexity. Control inputs support shutdown and operating-state management when a system needs to reduce power or isolate the interface.
Typical applications include industrial serial consoles, laboratory instruments, barcode and identification equipment, embedded control systems, and point-to-point links between a controller and peripheral. Because the interface uses single-ended RS-232 signaling, the board layout should keep the driver outputs and receiver inputs away from switching nodes and noisy analog sections.
Design the 5 V supply to remain within 4.5 V to 5.5 V, and follow the Analog Devices datasheet when selecting charge-pump capacitor voltage ratings, grounding, and protection networks. Confirm signal levels, receiver enable polarity, and connector pin assignments in the application circuit before layout release.
This product page organizes the manufacturer specifications, sourcing guidance, interface comparisons, pin-package constraints, and practical RS-232 design considerations needed to evaluate the ADM206ARZ as a multi-channel single-supply transceiver.

Tipikal na mga Gamit
ADM206ARZ ay nararapat para sa 6 aplikasyons: Industrial Control Console, Laboratory Instrumentation Interface, Point-to-Point Equipment Link, Embedded Data Acquisition System, Barcode and Identification Equipment, Service and Diagnostic Interface.
Industrial Control Console
The ADM206ARZ fits an industrial controller that must expose several RS-232 channels while operating from a 5 V logic rail. Four driver outputs can carry commands, status signals, or service data, while three receiver inputs support responses from attached equipment. Its 200 kbps maximum data rate is adequate for supervisory protocols and configuration links. The single-supply architecture removes separate ±12 V rails, while approximately ±9 V output swing improves signal margin. Designers should route each line to its assigned protection or connector circuit and verify the enable and shutdown polarity during firmware and hardware bring-up.
Inirekomenda
Laboratory Instrumentation Interface
A laboratory instrument can use the ADM206ARZ to consolidate several low-speed serial links between an instrument controller and measurement hardware. The four-driver arrangement supports commands and trigger information, while the three receivers can accept status or measurement acknowledgments. Its 200 kbps rating is suitable for many serial-control protocols, and the single 5 V supply simplifies analog and digital power planning. Approximately ±9 V line swing provides useful margin on the driver side. Keep sensitive analog and reference circuitry separated from charge-pump and driver return currents to reduce coupling into measurements.
Inirekomenda
Point-to-Point Equipment Link
The ADM206ARZ is appropriate for a point-to-point connection between a controller and a peripheral when multiple RS-232 channels are needed but a multi-drop bus is not required. Its full-duplex architecture allows command traffic and return data to use separate driver and receiver channels. The 200 kbps data rate covers moderate-speed configuration and status protocols. Operating from 4.5 V to 5.5 V permits use with conventional 5 V systems, while the internal charge pumps eliminate external bipolar supply requirements. Include suitable connector protection and confirm that ground potential differences remain within the interface’s application limits.
Inirekomenda
Embedded Data Acquisition System
An embedded acquisition controller can use the ADM206ARZ to connect sensor-processing boards, service ports, or external test fixtures through multiple RS-232 channels. The four drivers support outbound configuration and synchronization signals, and the three receivers accept returned data or acknowledgments. A 200 kbps link rate suits many low-bandwidth acquisition-control protocols. Because the transceiver requires only a 5 V supply, it can share regulated power with digital processing circuitry, although charge-pump return paths still require careful layout. The shutdown and enable controls also help systems manage interface power during idle or maintenance states.
Inirekomenda
Barcode and Identification Equipment
Barcode scanners, identification readers, and local service equipment can benefit from the ADM206ARZ when a product needs several RS-232 channels but not high-speed differential communication. The four transmitter channels can drive command, trigger, and status connections, while the three receiver channels handle incoming reader or peripheral responses. The 200 kbps maximum data rate supports common serial identification protocols. Its 5 V operating requirement simplifies integration with embedded control electronics, and the internal charge pumps reduce external component count. Verify connector pin assignments, handshake support, and cable shielding against the specific equipment protocol.
Inirekomenda
Service and Diagnostic Interface
Service technicians may connect a diagnostic host to embedded equipment through a board populated with the ADM206ARZ. Multiple driver and receiver channels allow diagnostic commands, operating parameters, and status messages to share the same interface device. The single 5 V supply is convenient for service cards and compact embedded systems, while the approximately ±9 V output swing supports dependable line levels. Shutdown can reduce power when no cable is attached, and enable control can support controlled activation of individual interface behavior. Add current-limited protection at externally accessible connectors and validate command framing before automatic diagnostics are enabled.

Talaan ng Disenyo
Power the ADM206ARZ from a regulated 4.5 V to 5.5 V source and verify the 5 V rail remains within range during transient loading. Place the charge-pump capacitors close to their designated pins with short, low-inductance connections, and follow the Analog Devices datasheet for capacitance tolerance and voltage-rating requirements.
Keep RS-232 driver traces away from sensitive analog inputs, clocks, and reference nodes. Route each driver and receiver pair deliberately, provide a continuous ground reference, and consider a shared ground connection near the cable entry. The ±9 V outputs must remain confined to the interface area and should not enter sensitive measurement regions.
Do not assume that two 24-pin SOIC RS-232 transceivers are interchangeable because their packages match. The ADM206ARZ has four drivers and three receivers, while the ADM207AR has five drivers and three receivers. Compare the complete pin-description table, enable polarity, shutdown behavior, and external capacitor requirements before approving a substitution.
External connectors should receive appropriate surge, ESD, and series-resistor protection selected for the cable environment. Validate receive thresholds, logic levels, and propagation behavior at the intended data rate. If the cable is long or crosses between equipment, add grounding and protection measures at the connector rather than relying solely on the transceiver’s internal line-driver capability.
