ISO1410DW - 500Kbps 5kVrms Isolated RS-485 | Texas Instruments
MPN: ISO1410DW ✓ فعالISO1410DW جائزہ
An isolated RS-485/RS-422 transceiver is an interface IC that converts logic-level signals into differential bus signals and receives differential bus signals back into logic-level outputs. Galvanic isolation places a reinforced isolation barrier between the bus-facing side and the logic side of the device. Within the product hierarchy, the ISO1410DW is a differential line transceiver, an interface IC, and a semiconductor designed for industrial networking and control systems.
The ISO1410DW's principal verified features include a maximum signaling rate of 500 Kbps, 5 kVrms isolation, half-duplex operation, RS-485 and RS-422 support, and robust EMC protection. Its 16-pin DW SOIC package provides sufficient pin count for the isolated transceiver interface, supply connections, bus terminals, and enable-related functions. The wide -40°C to +125°C temperature range makes it suitable for industrial equipment subjected to extended thermal conditions.
Texas Instruments describes the ISO14xx family as galvanically isolated differential line transceivers for TIA/EIA RS-485 and RS-422 applications. These noise-immune devices are designed for harsh industrial environments, and their bus pins are intended to withstand high levels of IEC electrostatic-discharge and electrical-fast-transient events. The manufacturer also provides the ISO1410DWEVM evaluation module for evaluating the ISO1410 in its 16-pin wide-body SOIC package.
Typical uses include isolated industrial bus links, factory automation equipment, building-control gateways, industrial sensors, and communication interfaces located at a significant ground-potential difference from the host controller. In these systems, the transceiver provides the physical-layer connection between a logic-side controller and a differential RS-485 or RS-422 bus. Half-duplex operation allows a shared pair of conductors to carry data in both directions, but bus direction must be managed by the host interface.
Designers should confirm the complete pinout, isolation requirements, bus termination strategy, fail-safe behavior, and external interface voltage levels against the manufacturer datasheet before layout. A 16-pin wide-body SOIC footprint should not be mixed with a narrow-body SOIC footprint, and the isolation barrier placement should follow the manufacturer's recommended layout and creepage guidance.
This page consolidates verified manufacturer and distributor information for ISO1410DW, including commercial availability, package details, application guidance, and a conservative drop-in replacement assessment. It also separates confirmed specifications from fields that require confirmation from the complete datasheet, helping engineers shorten component research without obscuring uncertainty.

Factory Automation RS-485 Links
ISO1410DW fits isolated factory-automation links that require reliable differential signaling at rates up to 500 Kbps. Its 5 kVrms galvanic-isolation barrier protects a controller from the bus-side environment, while the EMC-protected bus pins are designed to withstand high levels of IEC electrostatic-discharge and electrical-fast-transient events. The device operates in half-duplex mode, allowing bidirectional communication over shared RS-485 conductors when host-side direction control is implemented correctly. Its -40°C to +125°C rating supports industrial temperature ranges. The 16-pin wide-body SOIC package must be placed according to the manufacturer layout, with isolation-clearance and bus-protection requirements treated as critical design constraints.

Building Control Gateways
ISO1410DW is appropriate for building-control gateways that connect a central controller to remote RS-485 or RS-422 field equipment. The 500 Kbps maximum data rate supports common supervisory-control and data-acquisition traffic, while half-duplex operation reduces the number of conductors required by a multidrop bus. Its 5 kVrms isolation barrier helps separate logic-side circuitry from field-side grounding and transients, which is valuable when equipment spans multiple building zones. The -40°C to +125°C range covers wide environmental conditions. Designers should still verify the exact interface voltage, fail-safe thresholds, termination, and bus topology from the manufacturer datasheet before finalizing the gateway schematic.

Industrial Sensor Networking
ISO1410DW can connect an industrial sensor network when the remote bus operates at or below 500 Kbps and requires reinforced isolation from the host electronics. Differential RS-485 or RS-422 signaling supports noise-immune communication over longer cable runs than single-ended interfaces, while the transceiver's EMC protection is specifically intended for harsh industrial environments. Half-duplex mode suits shared multidrop sensor buses if transmit and receive periods are properly coordinated. The 16-pin wide-body SOIC format provides adequate isolation and bus routing area, but layout must preserve the manufacturer's barrier and creepage guidance. A separate isolated supply is required for remote sensor circuitry because the ISO1410 does not include integrated isolated power.

Isolated Data Acquisition
ISO1410DW is suitable for data-acquisition equipment that must communicate with remote sensors over RS-485 or RS-422 while maintaining galvanic isolation. The 500 Kbps rate provides ample bandwidth for many measurement and supervisory-control systems, and the half-duplex interface can reduce wiring by sharing conductors among multiple nodes. Its EMC-protected bus pins and -40°C to +125°C operating range are advantageous in electrically noisy environments. The isolation barrier should be positioned as the boundary between host electronics and external wiring, with bus protection and surge-current considerations handled separately. Exact input thresholds, propagation delay, and supply limits should be confirmed from the current ISO1410 datasheet before high-accuracy timing or signal-chain implementation.

Industrial Communication Port
ISO1410DW can serve as the isolated communications port in PLCs, remote I/O modules, and industrial controllers requiring an RS-485 or RS-422 physical layer. A 500 Kbps interface is suitable for high-speed token-passing or polled industrial traffic, while the 5 kVrms isolation barrier improves separation between the controller and field bus. The wide-body 16-pin SOIC footprint gives the layout more room than a narrow SOIC and matches the ISO1410DWEVM evaluation-module format. Designers should verify direction-control logic, fail-safe behavior, and isolation requirements. If the port also needs isolated power for external transceivers or sensors, a separate isolated converter is necessary because integrated isolated power is absent.

Long-Distance Industrial Networking
ISO1410DW is appropriate for long-distance industrial network segments that require robust differential signaling and reinforced isolation. RS-485 and RS-422 support at rates up to 500 Kbps gives designers a standardized physical-layer option for cable runs in factories, process equipment, and distributed control systems. The EMC-focused construction and bus-pin protection improve resilience to electrostatic discharge and electrical fast transients in harsh environments. Half-duplex RS-485 operation allows several nodes to share a bus, although termination, biasing, node count, and direction arbitration must be engineered for the complete network. The -40°C to +125°C rating broadens its use in temperature-variable installations, subject to application-specific qualification.

ڈیزائن نوٹس
Treat the isolation barrier as a PCB-layout constraint rather than only a schematic boundary. Place ISO1410DW so that no copper, test-point pad, or high-voltage isolation-network component crosses between the logic-side and bus-side regions. Use the current manufacturer DW package drawing and recommended layout for exact keepout dimensions. Confirm that the selected PCB stack-up and surface finish preserve the required creepage and clearance; the supplied snippets do not provide those dimensions.
Do not confuse ISO1410DWR with a different electrical transceiver. It is the tape-and-reel ordering form of the 16-pin DW device, whereas ISO1410DWEVM is an evaluation module and ISO1410BDW is the separately listed B-grade-family candidate. Likewise, the ISO1410 does not include integrated isolated DC-DC power. A field-side circuit requiring isolated power needs a separate converter. These distinctions prevent unnecessary PCB, sourcing, and system-architecture errors.
The ISO1410's integrated EMC characteristics improve bus robustness, but they do not eliminate external protection requirements. Keep the differential trace pair short and closely coupled, route it away from switching nodes and isolation-barrier crossings, and follow the datasheet's termination and component-placement recommendations. Verify grounding and surge strategy at the cable entry. The 500 Kbps rate can increase edge-related emissions and timing margin concerns on longer or poorly terminated cables.
Verify both isolated sides of the device against the current datasheet before assigning power rails or calculating dissipation. The supplied data confirms 5 kVrms signal-path isolation but does not include either supply-voltage range, so those values must not be assumed from the bus rating. Check the logic-side and bus-side voltage limits, quiescent demand, output-driver load, and thermal rise using the manufacturer's electrical characteristics and the actual PCB thermal environment.
تعمیل کی معلومات
The supplied verified excerpts mention IEC electrostatic-discharge and electrical-fast-transient robustness but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for ISO1410DW. Compliance fields are therefore left unknown rather than inferred.
