ISL8563IP - 3V-5.5V 250kbps RS-232 Interface | Renesas
The Renesas Electronics ISL8563IP is a 3V-to-5.5V powered RS-232 transmitter/receiver interface IC with a guaranteed minimum data rate of 250kbps and 1uA-class operational supply current. The device is packaged as ISL8563IP in a leaded plastic-style package identified by the IP ordering code. It integrates RS-232 drivers and receivers intended for low-voltage serial links, with compliance stated for EIA/TIA-562 and EIA/TIA-232 operation, including operation down to a 3.0V supply. An RS-232 transceiver is an interface IC that converts logic-level digital signals into RS-232 voltage levels and converts received RS-232 signals back into logic-compatible levels. Within the broader semiconductor hierarchy, it belongs to the interface IC family, alongside line drivers, receivers, transceivers, and communications interface devices. The ISL8563IP specifically addresses systems that need bidirectional serial communication without using a 5V-only RS-232 implementation. Three headline characteristics make the ISL8563IP useful in compact equipment. Its 3.0V-to-5.5V operating supply supports both 3.3V and 5V system rails. Its guaranteed 250kbps minimum data rate permits substantially faster communication than conventional low-speed serial links. Its 1uA operational supply current supports power-conscious portable equipment. The manufacturer datasheet also states that only four external 0.1uF capacitors are required, simplifying the surrounding analog and digital interface circuitry. Technically, the device combines powered transmitters and receivers designed to meet EIA/TIA-562 and EIA/TIA-232 specifications. The dual-standard positioning is important because EIA/TIA-562 was developed for lower-voltage RS-232-compatible links, while EIA/TIA-232 describes conventional RS-232 electrical characteristics. The verified device description explicitly confirms operation at VCC = 3.0V, rather than requiring the 5V supply traditionally associated with classic RS-232 parts. Typical uses include PDAs, palmtop computers, notebook computers, and other portable or compact systems with low-voltage RS-232 links. The ISL8563IP is also appropriate for point-to-point serial connections, equipment interfaces, and embedded control links where the system supply is 3.3V or 5V. Its 250kbps capability can shorten communication time when the connected equipment and protocol support that rate. A key design consideration is that the external capacitors must be placed close to their associated device pins, and the board must maintain adequate separation between RS-232 driver outputs and receiver inputs to limit noise coupling. Designers should also verify that the connected equipment uses compatible signal levels and baud rates. The verified material does not expose the complete pin assignment, so the published package drawing should be consulted before PCB routing. This product record combines verified electrical capabilities, sourcing information, availability data, and application guidance in one engineering-oriented reference. It also clearly distinguishes confirmed manufacturer specifications from unavailable details rather than estimating pin assignments, package dimensions, temperature limits, or lifecycle details.
ISO1042BQDWRQ1 - 5 Mbps Isolated CAN FD Transceiver | Texas Instruments
Texas Instruments ISO1042BQDWRQ1 is a galvanically isolated Controller Area Network transceiver supporting CAN FD data rates up to 5 Mbps and complying with ISO11898-2 (2016). It provides ±70 V DC bus fault protection, a ±30 V common-mode voltage range, and automotive-grade isolation in a 16-pin SOIC package. A CAN transceiver is the physical-layer interface between a CAN controller and the differential CAN bus. It converts logic-level TXD and RXD signals into CAN bus levels and receives bus activity for the controller. Galvanic isolation places a robust communication barrier between the bus-side circuitry and the logic-side circuitry, helping prevent ground-potential differences and high-energy bus faults from propagating into sensitive electronic systems. The ISO1042-Q1 family combines flexible data-rate operation with unusually strong bus fault tolerance. Its ±70 V DC bus fault protection exceeds the transient and fault voltages normally encountered in harsh vehicle environments, while the ±30 V common-mode range supports operation across nodes with significant ground offsets. CAN FD support allows higher payload throughput than classic CAN, helping reduce transfer time when larger data frames are needed. The device is intended for automotive and industrial networks in which robust isolation, high fault tolerance, and deterministic communication are important. Suitable uses include electric-vehicle power electronics, vehicle body controllers, battery-management systems, industrial automation equipment, and isolated diagnostic interfaces. The wide fault range is especially useful in environments where wiring faults, load dump events, or ground shifts can stress connected nodes. PCB layout is critical because the isolation barrier, bus traces, ground separation, and protection network must be implemented according to the manufacturer datasheet. Keep the isolated-side and logic-side copper regions separated, route the CANH and CANL pair as a balanced differential pair, and place bus-side protection components close to the connector. Maintain the specified creepage, clearance, capacitor, and termination arrangements to preserve isolation and communication reliability. This page combines the manufacturer device description, ordering information, verified product links, application guidance, and practical design notes to help engineers evaluate the ISO1042BQDWRQ1 for isolated CAN FD nodes. It also identifies same-footprint family alternatives while clearly separating verified product facts from parameters requiring confirmation in the datasheet.
ISO1042DW - 5Mbps Isolated CAN Transceiver | Texas Instruments
The Texas Instruments ISO1042DW is a galvanically isolated CAN transceiver with a 5 Mbps maximum data rate, reinforced isolation, and 16-pin wide-body SOIC (DW) packaging. It supports classic CAN operation up to 1 Mbps and CAN FD operation up to 5 Mbps while meeting the ISO 11898-2:2016 physical-layer standard. The device also provides ±70 V DC bus fault protection and a ±30 V common-mode voltage range. These specifications make it suitable for industrial, transportation, and other electrically noisy installations where a CAN node requires reinforced isolation from its host circuitry. An isolated CAN transceiver is a physical-layer interface device that couples a controller-area-network bus to digital logic while maintaining galvanic isolation between the two sides. In the hierarchy of electronic components, it belongs to the CAN transceiver class, then to wired network interfaces, communications ICs, and ultimately semiconductor devices. Isolation is especially valuable when ground-potential differences, high-energy bus faults, or long external cable runs could otherwise damage a controller or create an unsafe grounding path. The ISO1042DW combines several protective and performance features in one interface. Its 152 ns loop delay supports dependable communication at high CAN FD rates, while ±70 V DC bus fault protection tolerates severe DC faults on the bus side. The ±30 V common-mode range improves tolerance to voltage differences between the transceiver and other nodes. The device supports a 1.8 V to 5.5 V supply range and is offered in a 16-pin wide-body SOIC package for surface-mount assembly. Technically, the ISO1042 is divided into logic-side and bus-side functional regions by its reinforced isolation barrier. CAN TX and RX signals pass through this barrier to the bus interface, while bus fault energy is contained on the isolated side. The manufacturer datasheet states that the device meets ISO 11898-2:2016, provides a maximum data rate of 5 Mbps, and includes DC bus-fault and ESD protection features. Exact isolation lifetime, surge withstand, and detailed pulse ratings are not included in the supplied search data and should be confirmed in the full manufacturer datasheet before qualification. Typical applications include factory automation, industrial robot controllers, electric mobility systems, building controls, and isolated CAN-to-CPU communication links. In each case, the device can connect a host controller to a CAN FD bus while preserving galvanic isolation. Engineers should pay particular attention to bus-fault energy, common-mode transients, isolated-side supply requirements, and the grounding strategy when integrating the transceiver into a finished system. Layout guidance should preserve the isolation barrier by keeping logic-side and bus-side copper, components, and creepage paths appropriately separated. Place required input and output capacitors close to their associated pins, and avoid routing bus-side signals beneath the isolation region. Because the isolated bus side may encounter substantial fault voltage, PCB creepage, clearance, and protection-component selection deserve review under the final system voltage rules. This product page consolidates the verified manufacturer specifications, distributor pricing, package information, and qualified cross-reference results into an engineering-oriented resource. It also identifies where alternative data is unavailable, allowing designers to distinguish verified drop-in options from isolated-interface products that merely provide similar functionality without sharing the required footprint.
ISO1042DWR - 5 Mbps Isolated CAN Transceiver | Texas Instruments
The Texas Instruments ISO1042DWR is an isolated CAN transceiver with 70-V bus fault protection and flexible data rate, designed for industrial, automotive, and embedded CAN networks. It is specified in a 16-pin SOIC (DW) package and operates from -40 °C to +125 °C. The device supports a maximum data rate of 5 Mbps and operates with 1.8 V to 5.5 V logic-level supply input, matching the description supplied by the Texas Instruments product pages and distributor listings. An isolated CAN transceiver belongs to the CAN interface and bus-communication hierarchy. It combines a CAN controller-side logic interface, a CAN bus-side driver and receiver, and a galvanic isolation barrier between the two sides. This separation allows a controller and transceiver on one side of the system to communicate with a CAN bus node on the other side while reducing common-mode and ground-potential problems. The ISO1042 is therefore a transceiver rather than a standalone CAN controller; the host MCU or other logic device still handles protocol processing. The headline features are flexible data rate operation up to 5 Mbps, 70-V bus fault protection, reinforced isolation, and a 16-pin SOIC footprint. The bus-side protection is intended to improve tolerance during fault conditions where a CAN node may be exposed to excessive bus voltage. The flexible data-rate feature allows the same device to be used in networks operating at different speeds, while the isolation barrier supports designs where the CAN bus ground is not shared with the logic ground. Typical applications include industrial automation equipment, electric motor controls, building-control gateways, automotive body electronics, robotics, and CAN-based sensor networks. In a motor controller, the isolated interface helps separate the low-voltage control circuitry from the bus reference. In a gateway, the same isolation supports linking two domains that cannot share a common ground. The 16-pin SOIC package is also useful for designs that need a compact, surface-mount implementation without a high-speed differential connector. Designers should treat the ISO1042DWR as a bus-interface component and pay close attention to decoupling, termination, isolation-capacitor placement, and the difference between logic-side and bus-side supplies. The available verified web results provide the device identity, package, temperature range, data-rate capability, logic voltage range, and protection class, but they do not provide a complete pin-by-pin electrical table or detailed pricing for every quantity break. Those fields are marked accordingly rather than being inferred.
ISO1042DWV - 5 Mbps Reinforced Isolated CAN | Texas Instruments
The Texas Instruments ISO1042DWV is a digitally isolated CAN transceiver supporting classic CAN up to 1 Mbps and CAN FD up to 5 Mbps, with ±70 V DC bus-fault protection and a ±30 V common-mode voltage range in an 8-pin wide-body SOIC package. The DWV package provides reinforced isolation with a 5000 VRMS withstand rating and a specified loop delay of 152 ns. An isolated CAN transceiver is an interface IC that combines a CAN physical-layer driver and receiver with digital isolation between the bus and the logic-side controller. This device hierarchy—CAN transceiver, isolated interface IC, interface IC, and semiconductor—separates the noisy external bus from the host domain while preserving communication with a CAN controller. Galvanic isolation helps limit ground potential differences and improves fault containment in industrial, automotive, and transportation systems. The ISO1042DWV supports the ISO 11898-2:2016 physical-layer standard. Its principal protections include ±70 V DC bus fault protection and operation across a ±30 V common-mode range. These ratings are particularly useful in electrically noisy installations where ground shifts or accidental bus-to-ground faults can exceed normal CAN operating voltages. The 5 Mbps CAN FD capability also allows higher-throughput communication than the 1 Mbps classic CAN limit. The digital isolation barrier provides 5000 VRMS withstand capability, while the 152 ns loop delay supports deterministic signal propagation between the bus and logic domains. The device integrates a CAN transmitter, receiver, isolation barrier, and protection circuitry, reducing the number of external interface components required. Its wide-body SOIC package also provides increased pin spacing for isolation applications. Typical uses include isolated industrial CAN links, electric-vehicle subsystems, transportation equipment, robotics controllers, building automation, and high-voltage battery-management interfaces. In these systems, the ISO1042DWV can connect a bus through its CAN side while presenting conventional logic-level RXD and TXD signals to an isolated controller domain. PCB design must preserve the isolation barrier, route the CAN bus and transceiver output away from sensitive logic, and place protection and bypass components directly at the relevant pins. Bus shielding, a defined reference network, and appropriate common-mode termination should be validated at system level. The 8-pin SOIC-8 package must not be confused with narrower 8-pin SOIC variants or non-pin-compatible isolated CAN devices.

ISO1042QDWQ1 - 5 Mbps Isolated CAN FD | Texas Instruments
Texas Instruments ISO1042QDWQ1 is an automotive, galvanically isolated CAN transceiver with a 16-pin SOIC package. It supports CAN FD operation up to 5 Mbps and meets the ISO11898-2 (2016) specifications. The transceiver provides ±70-V DC bus fault protection and a ±30-V common-mode voltage range, making it suitable for CAN networks exposed to automotive electrical transients. A CAN transceiver, also called a CAN controller interface, connects a controller or microcontroller to a differential Controller Area Network bus. A controller area network is a deterministic, multiplexed communication system widely used in automotive electronics, industrial automation, and embedded control. The galvanically isolated implementation belongs to the interface IC hierarchy and creates a protective barrier between the bus-side circuitry and the logic-side circuitry. The ISO1042QDWQ1 combines several network-protection functions. Its ±70-V DC bus fault protection helps the device survive sustained DC faults on CANH or CANL. The ±30-V common-mode range allows the transceiver to operate when the bus nodes sit substantially above or below the local ground reference. CAN FD support up to 5 Mbps enables faster payload transfer than classic CAN while retaining a familiar CAN bus interface. Isolation is especially valuable when the CAN bus is electrically distant from the host electronics or when ground-offset conditions cannot be tightly controlled. By separating the bus-side and logic-side portions of the transceiver, the ISO1042QDWQ1 helps limit propagation of noise and fault energy. The automotive-qualified ordering option supports designs that require a component intended for extended-temperature automotive environments. Typical applications include electric vehicle powertrain controllers, body and comfort modules, battery-management systems, industrial vehicle networks, industrial automation equipment, and other embedded systems that combine CAN communication with high-side fault tolerance. The 5-Mbps capability is useful for gateways, diagnostics interfaces, and control modules moving more data than a classic CAN network. PCB design should preserve the isolation barrier between logic-side and bus-side copper, maintain the device’s recommended input and output capacitance, and route bus traces away from sensitive analog or high-speed digital signals. Decoupling capacitors should be placed close to their associated supply pins, while the CAN bus connections require careful return-path and surge-current planning. This page combines the manufacturer’s product specifications, drop-in family alternatives, parameter comparisons, and practical interface-design guidance. It also highlights the distinction between bus-fault protection, common-mode tolerance, CAN FD data rate, and galvanic isolation so engineers can evaluate the device against the actual electrical environment of the target network.
ISO1042QDWRQ1 - 5Mbps Isolated CAN FD | Texas Instruments
The Texas Instruments ISO1042QDWRQ1 is an automotive galvanically isolated CAN transceiver supporting data rates up to 5 Mbps and implemented in a 16-pin SOIC package. It meets ISO11898-2 (2016), provides ±70-V DC bus-fault protection, and operates across a ±30-V common-mode voltage range. The device combines a CAN controller-side interface with a bus-side transceiver in one isolated package. A CAN transceiver is the physical-layer interface between a CAN controller and a Controller Area Network bus. It converts logic-level transmit and receive signals into differential CAN bus signals, while providing galvanic isolation between those domains. This separation reduces ground-potential and fault-energy paths, making the transceiver suitable for electrically demanding automotive, industrial, and communications equipment that uses the ISO11898-2 CAN standard. Key features include a maximum data rate of 5 Mbps in CAN FD mode, ±70-V DC bus-fault protection, and a ±30-V common-mode range. The 16-pin SOIC package provides enough pins for the isolated logic interface, isolation barrier, CAN bus side, and bypass connections. The automotive-rated ISO1042-Q1 family is intended for systems where robust fault handling and high-speed CAN FD communication are important. The ISO1042-Q1 architecture separates the controller-side TXD and RXD signals from the CANH and CANL bus terminals with an internal isolation barrier. Its high fault tolerance lets the bus interface withstand severe DC bus faults without immediately compromising the logic side. During normal operation, the bus side supports high-speed CAN FD communication, while the isolated logic side connects to a CAN controller through digital transmit, receive, enable, and power connections. Typical uses include automotive body and chassis controllers, electric-vehicle power domains, industrial automation equipment, robotics, medical carts, and other embedded systems that need a robust isolated CAN interface. In an automobile, the transceiver can connect a low-voltage controller to a CAN bus exposed to battery transients and wiring faults. In factory equipment, isolation helps bridge control electronics and field-bus wiring across different ground references. Design the PCB with short CANH and CANL traces, a continuous return path beneath the bus pair, and the bus-side bypass capacitor placed close to the device. Keep isolation-side and bus-side copper areas separated according to the Texas Instruments datasheet layout guidance. The isolation barrier components and supply networks must also follow the specified creepage and clearance requirements, particularly in high-voltage automotive environments.
ISO1042QDWVQ1 - 5Mbps Isolated CAN FD | Texas Instruments

A CAN transceiver is the physical-layer interface between a CAN controller and a two-wire differential bus. ISO1042-family devices combine bus-driver and receiver functions with digital isolation, allowing a controller-side logic domain to communicate with a bus-side domain while reducing common-mode and ground-potential hazards. This transceiver belongs to the CAN interface IC, interface IC, and semiconductor hierarchy used in automotive and industrial networks. Key features include operation up to 5 Mbps in CAN FD mode, ±70-V DC bus fault protection, and a ±30-V common-mode range. The isolation barrier separates logic-side and bus-side circuits, while flexible data rate support permits substantially faster payload transfer than classical CAN. These characteristics suit systems that must combine high-speed data transfer with robust protection against automotive electrical transients. The ISO1042-Q1 family meets the ISO11898-2:2016 specification and is positioned for automotive and industrial CAN networks. Its primary interface functions include transmit, receive, bus-fault handling, and isolation. The 16-pin wide-body SOIC package supports surface-mount assembly while providing enough lead spacing for inspection and rework in demanding electronics manufacturing processes. Typical applications include electric-vehicle powertrain and body networks, industrial automation equipment, robotics controllers, diagnostic systems, and isolated CAN links between high-voltage systems and low-voltage controllers. In these systems, the isolated transceiver can link a CAN FD-capable controller to a protected network while helping maintain functional separation between circuit domains. Designers should pay close attention to bus termination, common-mode range, grounding, isolation-capacitor placement, and the exact pin assignments in the manufacturer datasheet. The 5-Mbps operating rate also requires controlled printed-circuit-board layout, short differential routing, and compliant CAN physical-layer timing. Automotive programs should additionally verify qualification, traceability, and sourcing requirements with the manufacturer. This page combines the manufacturer specifications, practical isolation-interface guidance, a same-package replacement comparison, and selection criteria that help engineers distinguish electrical protection, automotive qualification, and interface compatibility before committing a board design.
ISO1042QDWVRQ1 - Isolated CAN Transceiver 5Mbps 8-SOIC | TI
The Texas Instruments ISO1042QDWVRQ1 is an automotive-grade, galvanically-isolated controller area network (CAN) transceiver that meets the ISO11898-2 (2016) standard, delivering up to 5 Mbps data rate in CAN FD mode and housed in an 8-pin SOIC (DWV) package with 2.5 kV RMS isolation (per VDE 0884-11). An isolated CAN transceiver is a type of bus interface IC that combines a standard CAN physical-layer transceiver with on-chip galvanic isolation. The ISO1042QDWVRQ1 sits between a microcontroller's CAN controller and the physical CAN bus, eliminating ground loops, blocking high common-mode transients, and protecting low-voltage domain circuitry from hazardous bus-side faults. In the broader taxonomy, this device is an isolated transceiver -> CAN transceiver -> bus interface IC -> interface IC -> signal-conditioning/isolation semiconductor. Key features include ±70-V DC bus fault protection (the highest in TI's automotive isolated CAN family), ±30-V common-mode voltage range for robust operation in 12 V and 24 V automotive/industrial buses, 5 Mbps CAN FD flexible data rate support, 1.7 V to 5.5 V logic-side supply with 4.5 V to 5.5 V bus-side supply, and 250 kV/µs typical common-mode transient immunity (CMTI). The half-duplex DWV variant consumes only one logic-side channel and supports a wide -40°C to +125°C operating range qualified to AEC-Q100 Grade 1 for automotive use. The device uses TI's proprietary silicon-dioxide (SiO2) capacitive isolation barrier coupled with an integrated differential CAN PHY. The internal architecture separates the digital interface (TXD, RXD, controller-side supply) from the bus-side driver/receiver with a reinforced isolation barrier rated for 400-VRMS or 2.5 kVRMS working voltages. This eliminates the need for external isolators, optocouplers, or discrete isolated DC-DC converters, reducing PCB area by up to 50% versus optocoupler-based discrete implementations. Typical applications include automotive body and chassis ECUs (BCM, gateway modules), electric vehicle battery management system (BMS) communication, industrial CANopen networks, solar inverter communication buses, PLC distributed I/O, and any 12 V / 24 V system that requires robust CAN communication with reinforced isolation. Designers select the ISO1042QDWVRQ1 when regulatory isolation certification, automotive-grade qualification, and high bus fault tolerance are simultaneously required. Design tip: the bus-side VCC2 pin must be supplied from a 4.5 V to 5.5 V rail; a low-ESR 1 µF to 10 µF ceramic decoupling capacitor placed within 2 mm of VCC2 is required. The logic-side VCC1 can run from 1.7 V to 5.5 V, allowing direct connection to 1.8 V, 3.3 V, or 5 V MCUs without level translation. This page synthesizes distributor pricing, drop-in alternative listings, and practical design notes not found in the manufacturer datasheet.
ISO1044BD - 5 Mbps Galvanically Isolated CAN FD | Texas Instruments
The Texas Instruments ISO1044BD is a galvanically isolated CAN FD transceiver with a 5 Mbps maximum data rate, ±58 V DC bus-fault protection, and a ±12 V common-mode operating range, housed in an 8-pin SOIC package. It is designed for CAN networks that require reinforced electrical isolation between the bus and the host electronics. An isolated CAN transceiver is an interface circuit that transfers CAN signals across a galvanic isolation barrier while protecting the connected controller from voltage differences, ground faults, and bus transients. The ISO1044BD is a half-bus CAN transceiver within the broader hierarchy of CAN interface ICs, interface ICs, and industrial communication semiconductors. Its isolation barrier helps prevent ground-loop current and improves fault containment in industrial equipment. The device meets ISO11898-2 (2016) and supports CAN FD operation up to 5 Mbps. The ISO1044B family provides ±58 V DC bus-fault protection and tolerates ±12 V common-mode voltage. The manufacturer describes the isolation rating as 5000 Vrms reinforced, while the SOIC-8 package reduces board area compared with a discrete optocoupler-based isolation implementation. The ISO1044BD integrates the CAN physical-layer transceiver and isolation barrier into one package. The digital CAN TX and RX interfaces remain electrically separated from the CAN bus side, allowing the transceiver to operate with the local logic supply and ground referenced to the controller. CAN FD increases payload capacity compared with classic CAN while retaining compatibility with established CAN network architecture. Typical uses include industrial automation controllers, electric motor drives, robotics, building automation, CAN-based sensors, and isolated service interfaces. It is particularly suitable when ground potentials can vary between equipment cabinets or when a bus fault could otherwise transfer damaging energy into the control system. Designers should use the manufacturer-specified CAN bus protection network, isolation capacitors, and PCB creepage and clearance rules. The SOIC-8 package still requires careful isolation-barrier routing; copper, solder mask, and component placement must not bridge the isolated and non-isolated domains. This product page consolidates verified manufacturer capabilities, distributor availability, comparison parameters, and practical isolation-layout guidance, adding engineering context beyond the basic manufacturer product summary while clearly identifying specifications that still require confirmation from the full datasheet.
ISO1050DWR - 5V Isolated CAN Transceiver | Texas Instruments
The Texas Instruments ISO1050DWR is a galvanically isolated CAN transceiver meeting the specifications of the ISO11898-2 standard. It provides a 1/1 isolated half CANBus interface, separates logic-side and bus-side buffers with a silicon oxide (SiO2) insulation barrier, and supports isolation up to 5000 V RMS for ISO1050DW. The device is packaged in a 16-pin SOIC and is intended for industrial communication systems where ground-potential differences and high common-mode bus noise must be contained. An isolated CAN transceiver is a network interface IC that combines CAN physical-layer signaling with a galvanic isolation barrier. It belongs to the broader hierarchy of CAN transceiver, isolated interface IC, industrial communication interface, and semiconductor. The ISO1050DWR allows a CAN controller or microprocessor on the logic side to communicate with a CAN bus through the isolated bus side, while preventing ground currents and high-voltage transients from propagating across the barrier. Key verified features include ISO11898-2 compliance, isolated 5 V CAN operation, 16-pin SOIC packaging, and a 1/1 transceiver configuration. The manufacturer specifies 5000 V RMS isolation for the ISO1050DW package variant and 2500 V RMS for the ISO1050DUB variant. The silicon oxide insulation barrier is intended to suppress noise and prevent dangerous ground loops in industrial environments. The ISO1050DWR is suited to industrial automation, transportation equipment, building controls, and isolated CAN networks. Its logic-side interface connects to a CAN controller, while the bus-side interface connects to CAN_H and CAN_L conductors. The isolated transceiver should be used with an isolated power supply so that the isolation barrier is not undermined by a shared ground path. A key design consideration is that isolation does not eliminate the need for correct bus termination, common-mode protection, or isolated-supply design. The 16-pin SOIC footprint supports conventional surface-mount assembly, while the tape-and-reel designation identifies the production packing format for high-volume manufacturing. This page combines verified manufacturer and distributor information with practical design guidance for isolated CAN implementations.
ISO1211D - 24V-60V Isolated Digital Input | Texas Instruments
The Texas Instruments ISO1211D is a single-channel isolated digital input receiver designed for 24V to 60V digital input modules, with an 8-pin SOIC (D) package. It supports 9V to 300V DC and AC input designs when used with external resistors, while providing accurate current limiting for low-power dissipation. The device targets PLC digital input interfaces and industrial control systems. An isolated digital input receiver converts field-side voltage states into a logic signal presented to a controller or other electronics. The ISO1211 belongs to the isolated-interface IC hierarchy and replaces conventional optocoupler input stages with an integrated receiver designed for high-side industrial input conditions. Its isolation function protects control-side circuitry from field-side electrical conditions while transferring the input state. Key verified features include compliance with IEC 61131-2 Type 1, 2, and 3 characteristics for 24V isolated digital inputs, bipolar input support, broken-wire detection, and an operating temperature range from -40C to +125C. The current limit is specified as 2.2mA to 2.47mA for Type 3 designs. The SOIC package provides eight terminals and is identified by TI as package code D. The ISO1211D is intended for programmable logic controllers, motor-control systems, grid infrastructure, and other industrial equipment with isolated digital inputs. External resistors set the supported field-input voltage range, so the final input network must be selected according to the intended DC or AC voltage and the applicable IEC 61131-2 input type. The receiver architecture allows the field interface to be designed without reproducing a discrete optocoupler circuit. Designers should verify the complete pinout, isolation requirements, resistor values, voltage ratings, and input thresholds against the manufacturer datasheet before production. The verified product page identifies ISO1211D as an 8-pin SOIC (D) device rated from -40C to +125C. Its principal engineering value is integration of a field-input receiver into a compact, application-specific interface for industrial control equipment. This page consolidates verified manufacturer and distributor information, IEC 61131-2 compatibility information, package data, application context, and design guidance. It does not infer unreported electrical values, invent pricing, or substitute a different package simply to create an alternative.

The ISO1211 belongs to the isolated-interface IC hierarchy and replaces conventional optocoupler input stages with an integrated receiver designed for high-side industrial input conditions. Its isolation function protects control-side circuitry from field-side electrical conditions while transferring the input state. Key verified features include compliance with IEC 61131-2 Type 1, 2, and 3 characteristics for 24V isolated digital inputs, bipolar input support, broken-wire detection, and an operating temperature range from -40C to +125C. The current limit is specified as 2.2mA to 2.47mA for Type 3 designs. The SOIC package provides eight terminals and is identified by TI as package code D. The ISO1211DR is intended for programmable logic controllers, motor-control systems, grid infrastructure, and other industrial equipment with isolated digital inputs. External resistors set the supported field-input voltage range, so the final input network must be selected according to the intended DC or AC voltage and the applicable IEC 61131-2 input type. The receiver architecture allows the field interface to be designed without reproducing a discrete optocoupler circuit. Designers should verify the complete pinout, isolation requirements, resistor values, voltage ratings, and input thresholds against the manufacturer datasheet before production. The verified product page identifies ISO1211DR as an 8-pin SOIC (D) device rated from -40C to +125C. Its principal engineering value is integration of a field-input receiver into a compact, application-specific interface for industrial control equipment. This page consolidates verified manufacturer and distributor information, IEC 61131-2 compatibility information, package data, application context, and design guidance.

ISO1410BDW - 500kbps Isolated RS-485/RS-422 | Texas Instruments
The Texas Instruments ISO1410BDW is an EMC-protected, galvanically isolated RS-485/RS-422 transceiver rated for data rates up to 500 kbps and half-duplex communication. The device is packaged in a 16-pin wide-body SOIC (DW) package and operates from -40°C to +125°C. Its 5 kVrms isolation rating and integrated digital isolation separate the bus-side interface from the logic-side circuitry, helping protect sensitive host electronics from ground-potential differences and industrial transients. The transceiver supports both RS-485 and RS-422 applications and is intended for factory automation, industrial control, building automation, and other electrically noisy environments. An isolated RS-485/RS-422 transceiver combines differential bus signaling, galvanic isolation, and logic-side interfacing. RS-485 is commonly used for multipoint, half-duplex industrial buses, while RS-422 provides differential signaling for communication between two endpoints. In the power-management and interface hierarchy, this device is a digital isolator combined with a physical-layer line transceiver rather than a protocol converter or a general-purpose logic IC. Its capacitive-isolation architecture separates data across the isolation barrier while the transceiver drives or receives differential bus signals. Key features include support for signaling rates up to 500 kbps, half-duplex operation, EMC-focused bus-pin protection, 5 kVrms isolation, and operation across the full -40°C to +125°C temperature range. The 16-pin DW package provides a wide-body surface-mount footprint with sufficient lead spacing for industrial assembly workflows. The availability of a half-duplex architecture allows a controller to share a communication channel for command and response traffic when the bus is idle. The ISO1410 product family is positioned between lower-rate and very-high-speed isolated serial interfaces. The supplied TI family description identifies ISO141x devices as supporting up to 500 kbps, while ISO143x devices support up to 12 Mbps and ISO145x devices up to 50 Mbps. This distinction matters when selecting a replacement because signal rate, bus timing, and isolation implementation must match the original design intent. The ISO1410BDW is therefore most appropriate where 500 kbps operation and EMC resilience are sufficient but higher throughput is unnecessary. Typical uses include industrial RS-485 buses, programmable logic controller communication, factory equipment interfaces, industrial sensor gateways, building-control networks, and isolated host connections. In these systems, the transceiver converts logic-level data into differential RS-485 or RS-422 signals, while its isolation barrier reduces the effect of unequal ground potentials between a controller and field equipment. A termination strategy, biasing network, protective earth connection, and correctly designed transceiver interface remain necessary for reliable operation. A key design consideration is that isolation does not remove the need for careful bus implementation. The logic and bus-side supply domains should be decoupled appropriately, and the differential pair should be routed as a controlled-impedance network with minimized stub lengths. Designers should also verify the required data rate, cable length, termination values, grounding strategy, and transient requirements against the complete system rather than treating the IC as a complete surge-protection solution. This product page combines verified manufacturer and distributor information, package and ordering data, comparison criteria, and application-oriented engineering guidance. It also distinguishes documented drop-in options from related family members and identifies where additional verification is required before replacing an installed ISO1410BDW.

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.

The principal features of the ISO1432 include a 12-Mbps data rate, 5-kVrms isolation, full-duplex operation, and EMC protection. The 12-Mbps capability provides sufficient bandwidth for factory automation, industrial data links, and peripheral interfaces while preserving the noise immunity associated with differential signaling. Its 5-kVrms isolation rating helps separate equipment domains that may experience substantial voltage differences or ground transients. The device supports both RS-485 and RS-422 applications in the same transceiver architecture. These standards use balanced differential signaling to reduce susceptibility to externally coupled noise, while the integrated isolation barrier adds another layer of protection. The ISO1432 is positioned for harsh industrial environments where bus pins may encounter electrostatic-discharge and electrical-fast-transient events, reducing the need for additional external protection in appropriately designed systems. Typical uses include industrial automation controllers, factory-floor communication links, grid infrastructure equipment, isolated data-acquisition systems, and point-to-point communications between equipment cabinets. Its full-duplex configuration can simplify bidirectional communication architectures because transmit and receive paths operate independently rather than sharing a single half-duplex bus direction control. The principal design consideration is the isolation and protection network around the bus interface. Follow the manufacturer datasheet for the exact external network, bypass-capacitor, termination, and bus-protection recommendations. Confirm that the system ground arrangement, cable length, baud rate, grounding method, and environmental ESD/EFT requirements are compatible with the ISO1432 operating limits before releasing the PCB design. This page combines the manufacturer’s key device characteristics, same-footprint alternatives, comparison parameters, and practical interface-design guidance. It emphasizes the ISO1432’s role as a 12-Mbps, full-duplex, 5-kVrms-isolated transceiver and helps engineers distinguish it from lower-speed, half-duplex, or differently isolated interface devices before making a board-level selection.
