MAX1480ECCPI+ - Isolated RS-485/RS-422 Transceiver | Analog Devices
Référence : MAX1480ECCPI+ ✓ ActifMAX1480ECCPI+ Présentation
An RS-485/RS-422 transceiver is an interface integrated circuit that combines differential line-driver and receiver functions for reliable, noise-resistant data transmission over balanced wiring. The MAX1480ECCPI+ belongs to the broader interface IC hierarchy, where it connects digital logic to industrial communication buses. Its isolated transmitter and receiver reduce conductive noise paths between a host system and an external RS-485 or RS-422 network, improving robustness where ground-potential differences or long cables are concerns.
Key characteristics include ±15 kV ESD protection, 4.5 V to 5.5 V operation, one differential driver, one differential receiver, and operation with both RS-485 and RS-422 networks. The 28-pin PDIP package supports through-hole assembly and straightforward inspection or rework. The component is specifically listed for new designs by the manufacturer through the MAX1480E family page.
The MAX1480ECCPI+ combines a data-interface transceiver with isolation in a single package. This simplifies board partitioning compared with a non-isolated transceiver plus separate isolation components. Isolation-related timing, creepage, capacitance, and transient-protection details should nevertheless be checked against the complete manufacturer datasheet before finalizing a high-speed or high-noise design.
Typical applications include isolated industrial RS-485 links, factory automation equipment, building-control systems, instrumentation, data acquisition, and communications equipment. The differential interface is particularly useful when the bus must tolerate electrically noisy industrial environments while maintaining a clear separation between equipment-ground domains.
Designers should preserve the recommended isolation barrier, provide adequate input and output bypassing, route the isolated bus through appropriately protected interfaces, and account for connector-level surge and ESD requirements. The ±15 kV device rating does not eliminate the need for correct system grounding, cable routing, and external protection.
This product page consolidates the manufacturer family information, interface characteristics, drop-in family alternatives, and application-specific engineering guidance. It is intended to help designers evaluate the MAX1480ECCPI+ for isolated RS-485 and RS-422 communication systems without relying on isolated snippets from individual listings.

Applications typiques
MAX1480ECCPI+ convient pour 6 applications: Isolated Industrial RS-485 Links, Factory Automation Data Acquisition, Building Control Networks, Instrumentation and Test Equipment, Industrial Sensor and Actuator Interfaces, Remote Communication Gateways.
Isolated Industrial RS-485 Links
The MAX1480ECCPI+ fits isolated industrial RS-485 links because it combines one differential driver, one differential receiver, a 4.5 V to 5.5 V supply range, and ±15 kV ESD protection in a 28-pin PDIP package. Place it between the host UART or logic interface and a balanced field bus, observing the isolation barrier and grounding arrangement in the manufacturer application guidance. Isolation helps interrupt low-frequency ground-current paths between equipment and the bus, while the differential receiver rejects common-mode noise encountered in industrial wiring. The ±15 kV rating strengthens transient resilience, although connector surge protection and controlled cable routing remain important for complete lightning or switching-energy protection.
Recommandé
Factory Automation Data Acquisition
The MAX1480ECCPI+ is appropriate for factory-automation data-acquisition modules that must communicate over RS-485 while separating the controller from field equipment. Its single driver and single receiver suit point-to-point or multidrop bus nodes, and its 4.5 V to 5.5 V operating range integrates with conventional 5 V digital systems. The isolated interface reduces ground-potential and conducted-noise concerns between a controller cabinet and remote sensors or actuators. Designers should still evaluate bus loading, termination strategy, stub lengths, and the maximum data rate for the selected cable before approving the communication path.
Recommandé
Building Control Networks
The MAX1480ECCPI+ can support isolated RS-485 communication between building controllers, room modules, and field equipment operating from different electrical domains. Its galvanized isolation, ±15 kV ESD protection, and support for RS-485/RS-422 help create a robust interface for long balanced cables in commercial building systems. The PDIP package permits straightforward through-hole assembly and inspection, which can simplify maintenance or replacement in controller assemblies. Installation practice remains critical: keep communication wiring away from high-energy switching circuits, maintain the intended isolation boundaries, and apply appropriate surge protection at the external cable entry.
Recommandé
Instrumentation and Test Equipment
The MAX1480ECCPI+ is useful in instrumentation and test equipment that must exchange RS-422 or RS-485 commands with an external device while protecting the sensitive host electronics. The one-driver, one-receiver arrangement provides the core balanced-line functions required by these interfaces, while isolation helps contain ground-offset effects between laboratory equipment and external fixtures. Its ±15 kV ESD protection adds useful robustness at the transceiver pins, while the 28-pin PDIP format supports conventional through-hole construction. Before choosing the device, verify cable length, signaling rate, receiver thresholds, isolation capacitance, and timing against the complete manufacturer data sheet.
Recommandé
Industrial Sensor and Actuator Interfaces
The MAX1480ECCPI+ can connect a controller to remotely located sensors, actuators, or motor-control modules that use balanced RS-485 communication. Its isolated interface reduces the chance that bus transients or unequal ground potentials will directly disturb the controller, and ±15 kV ESD protection strengthens the interface against electrostatic discharge events. The 4.5 V to 5.5 V supply range aligns with 5 V embedded systems. Designers should use a controlled bus topology, install termination only where required by the network design, avoid excessive stub lengths, and confirm that the interface timing supports the selected baud rate and cable distance.
Recommandé
Remote Communication Gateways
The MAX1480ECCPI+ is appropriate for remote gateways that terminate an RS-485 or RS-422 industrial segment and bridge it to local digital logic. The transceiver’s isolated differential interface helps protect the gateway electronics from common-mode noise and ground-potential differences on field wiring. Its single driver and receiver make it a practical choice for bus nodes that require one bidirectional communication path, while the 28-pin PDIP package is compatible with through-hole board assembly. For gateway deployments, engineers should evaluate galvanic-isolation capacitance, data-rate limits, cable characteristics, and whether an additional external surge-protection network is needed.

Notes de conception
Keep the logic-side and bus-side copper regions separated according to the isolation guidance in the MAX1480E manufacturer data sheet. Avoid placing high-current or high-voltage switching traces beneath or across the isolation barrier. Place input and output bypassing capacitors at the device pins as shown in the recommended application circuit, and preserve the required creepage and clearance distances on the PCB.
Do not assume that the ±15 kV ESD rating covers lightning, motor-switching, or industrial-surge events. The external connector and cable entry may require coordinated surge protection, while the bus must use a proper topology, controlled stub lengths, and termination only where the network design calls for it. Also verify whether the application requires half-duplex RS-485 operation or full-duplex RS-422 wiring.
Place the MAX1480ECCPI+ so the 28-pin PDIP remains accessible for inspection and rework, especially in industrial equipment where maintenance may occur after installation. Keep the isolated transceiver away from high-current power stages and noisy switching nodes. Use a defined ground strategy for the logic side and avoid unintended copper paths that could undermine the intended isolation boundary.
Validate the completed bus rather than relying only on the transceiver specification. Check cable impedance, connector losses, branch or stub length, termination, common-mode range, and the required signaling rate against the MAX1480E data-sheet limits. If replacing MAX1480ECCPI+ with another ordering suffix, confirm receiver thresholds, timing, isolation capacitance, and temperature-range equivalence before production release.
