ISL8489IP - 5V 250kbps Full-Duplex RS-485/422 | Renesas
Renesas Electronics ISL8489IP is a 5 V, low-power, full-duplex RS-485/RS-422 transceiver capable of operation at 250 kbps and packaged in a 14-pin PDIP. The device combines one driver and one receiver in a single package, supports balanced differential communications, and provides a slew-rate-limited alternative for systems that require reduced signal-edge velocity. Its operating characteristics are suited to industrial, instrumentation, communications, and embedded data-acquisition equipment that must connect a host or controller to a balanced bus. An RS-485/RS-422 transceiver is an interface IC that converts logic-level signals into balanced differential transmissions and converts received differential signals back into logic levels. RS-485 supports multipoint bus communication over long cable runs, while RS-422 commonly supports point-to-point and one-driver topologies. A full-duplex transceiver provides separate paths for transmitting and receiving, unlike half-duplex designs that share a bus and require direction-control logic. The ISL8489IP therefore fits designs that need simultaneous bidirectional communication without sharing a physical signal pair. Key verified features include a 5 V supply requirement, a maximum signaling rate of 250 kbps, full-duplex operation, support for both RS-485 and RS-422, low-power operation, and a slew-rate-limited operating option. The 14-pin PDIP package also provides through-hole compatibility for equipment requiring sockets, prototyping, or manually assembled industrial control boards. The indexed descriptions do not specify separate receiver-enable or transmitter-enable controls, indicating that this version is intended for continuous full-duplex operation. The transceiver architecture provides differential signaling, which is valuable in environments containing industrial machinery, switching supplies, and long interconnects. Differential voltage is measured between the two conductors of a pair rather than relative to ground, improving noise immunity on the receive side. The 250 kbps rate is appropriate for low-to-moderate-speed control and monitoring links where higher signaling rates are unnecessary. The slew-rate-limited behavior can help reduce edge-related ringing and electromagnetic interference when implemented with a correctly terminated network. Typical applications include industrial sensor and actuator networks, factory equipment links, building-control interfaces, laboratory instrumentation, point-to-point data links, and RS-422-compatible control systems. In these systems, the transceiver can connect a UART or microcontroller serial port to a balanced bus. Designers should still verify cable length, topology, grounding, termination, and logic-level compatibility against the complete system requirements before production release. A key design consideration is that the 14-pin PDIP package is not as compact as a surface-mount transceiver. It nevertheless simplifies through-hole construction and socket-based maintenance. The principal engineering trade-off is between 250 kbps operation, low power, full-duplex behavior, and the practical size and assembly requirements of a 14-pin through-hole package. This page consolidates the verified distributor and manufacturer-datasheet indexing information for the ISL8489IP with product-specific engineering guidance, specification gaps, and a transparent replacement assessment. It does not infer unseen electrical limits or substitute candidates whose pin compatibility has not been demonstrated.
ISL8490IB - 5V Low-Power RS-485/RS-422 Transceiver | Renesas
Renesas ISL8490IB is a 5V, low-power RS-485/RS-422 interface transceiver packaged in an 8-pin SOIC. It is designed for balanced serial data links that require the physical signaling characteristics of both RS-485 and RS-422 interfaces. The verified source material identifies the ISL8490 as a single transceiver supporting high-speed operation or slew-rate-limited operation, allowing it to suit point-to-point RS-422 links as well as multipoint RS-485 networks when used with appropriate bus termination and biasing. Its interface role places it within the transceiver and line-driver hierarchy of communication interface ICs. An RS-485 transceiver converts logic-level digital information into differential signals suitable for balanced industrial communication cables. Differential signaling provides resistance to common-mode noise and allows communication over longer cable runs than a single-ended interface. An RS-422 transceiver similarly uses differential signaling, normally in a point-to-point topology. The ISL8490IB therefore serves as an interface between a digital controller or host and physical copper wiring while placing the high-voltage, high-current bus activity on the transceiver side of the circuit. The principal verified feature is its 5V supply operation. This places it among low-voltage CMOS interface devices intended for systems with compatible digital logic rails. The part is described as low power and as supporting either high-speed or slew-rate-limited communication. High-speed operation prioritizes data throughput, while slew-rate limiting reduces transition-edge energy and can help control electromagnetic interference and ringing on slower networks. Exact data-rate, supply-current, differential-output, input-threshold, and temperature-range values must be confirmed in the manufacturer datasheet before a design is released. Typical uses include industrial RS-485 links, point-to-point RS-422 interconnects, instrumentation, factory automation, building controls, and embedded communication networks. In each case, the transceiver is placed between the controller UART or logic interface and the A/B differential pair. Appropriate cable routing, common-mode grounding, surge protection, termination, and fail-safe biasing remain important parts of the complete interface. Designers should preserve the exact pin mapping and verify the required driver-enable, receiver-enable, termination, and exposed-pad details against the ISL8490 manufacturer datasheet. This page consolidates verified product identity, package information, source links, application guidance, and engineering considerations that are not presented together on a basic distributor listing.
ISL8490IP - 5Mbps RS-485/RS-422 Transceiver | Renesas
The Renesas Electronics ISL8490IP is a 5 V, low-power, full-duplex RS-485 and RS-422 interface transceiver with one driver and one receiver, a maximum data rate of 5 Mbps, and an 8-pin PDIP package. The device supports both high-speed RS-485 communication and RS-422 point-to-point links, while its separate receiver and driver enable paths provide flexibility for half-duplex control through the DE and RE inputs. Its operating-temperature range is -40°C to +85°C, making it suitable for industrial and commercial equipment requiring a through-hole interface solution. A transceiver is an interface IC that converts digital logic signals into balanced differential signals for reliable communication over noisy or long cable runs. In the hierarchy, the ISL8490IP is a line transceiver, a type of interface IC and communications semiconductor. RS-485 supports multiple drivers and receivers on a shared bus, whereas RS-422 commonly uses a dedicated driver and receiver for point-to-point or multidrop networks. This transceiver supports both protocols and therefore provides a useful interface between CMOS/TTL logic and balanced cabling. The verified headline specifications are a 5 V supply, 5 Mbps maximum data rate, 70 mV receiver hysteresis, 1 driver, 1 receiver, full-duplex operation, and support for RS-422 and RS-485. These parameters place the part in the low-power, high-speed or slew-rate-limited transceiver category described by the manufacturer documentation. The 8-pin PDIP format also permits conventional through-hole PCB assembly rather than requiring a fine-pitch surface-mount land pattern. Technically, the balanced driver and receiver provide noise immunity over longer interconnects than ordinary single-ended logic. Receiver hysteresis helps distinguish signaling states in the presence of noise, while the 5 Mbps capability supports communication rates beyond the slow speeds commonly used by legacy RS-485 systems. Because the exact input capacitance, output timing, supply-current limits, and slew-rate settings are not included in the supplied verified excerpts, design engineers should confirm them in the manufacturer datasheet before finalizing timing, termination, and decoupling. Typical uses include industrial controllers, building automation equipment, data acquisition systems, instrumentation, industrial networking equipment, and embedded control links. For an RS-485 bus, the circuit requires suitable line termination and biasing. For RS-422, driver and receiver connections should follow the source and destination topology specified by the system architecture rather than being treated as a multi-drop RS-485 bus. The principal design consideration is signal integrity at 5 Mbps. Layout should minimize the distance between the transceiver, protection devices, connector, and differential pair, while keeping the two conductors of each balanced pair closely coupled. Decoupling close to the supply pin, controlled ground return paths, and appropriate surge protection help maintain reliable operation in industrial environments. This page consolidates the verified distributor and manufacturer-document information with lifecycle status, procurement guidance, application fit, package details, and honest replacement limitations. It distinguishes confirmed facts from specifications that still require verification from the full Renesas datasheet.

It combines one driver and one receiver in a single balanced-communications device, providing the core physical-layer functions required for point-to-point RS-422 links and multipoint RS-485 buses. The verified manufacturer and distributor records identify the device as a 14-SOIC, full-duplex RS-485/RS-422 transceiver with high-speed or slew-rate-limited operation. An RS-485/RS-422 transceiver is an interface IC that converts logic-level signals into balanced differential line signals and reconstructs logic-level data from those differential signals. The differential signaling belongs to the transceiver class within interface ICs, data communications, and the broader semiconductor hierarchy. Balanced operation improves noise immunity by deriving the received state from the voltage difference between two conductors rather than relying on a signal measured relative to ground alone. The principal identified features of the ISL8491IB are its 5V CMOS-style supply operation, low-power architecture, full-duplex configuration, and support for both RS-485 and RS-422 communication standards. Because it contains one transmitter and one receiver, the part can support simultaneous transmit and receive paths when the host or controller provides separate request and data-bus signals. The verified distributor description also identifies variants capable of high-speed or slew-rate-limited operation, allowing engineers to compare communication behavior and system timing requirements. The ISL8491IB is suitable for industrial data links, industrial automation equipment, instrumentation, building-control networks, and embedded systems that exchange data over balanced copper cabling. Its 14-pin SOIC package supports conventional surface-mount PCB assembly, while the full-duplex arrangement avoids sharing one physical pair between opposing directions. Designers must still provide suitable logic interfacing, termination, biasing, grounding, and protection appropriate to the cable length, data rate, and industrial environment. A critical design consideration is that the transceiver's communication mode and electrical settings must match the network topology. RS-422 generally supports a point-to-point driver relationship, while RS-485 permits multiple drivers on a bus but requires careful idle-state biasing and termination. The exact driver strength, receiver thresholds, data rate, common-mode range, ESD rating, and pin-level truth table are not supplied in the verified data and should be confirmed in the manufacturer datasheet before layout or production use. This page consolidates the verified distributor and manufacturer references for the ISL8491IB, distinguishes the device from general-purpose interface ICs, and provides sourcing, selection, replacement, and application guidance. It also records uncertain specifications explicitly rather than substituting estimates, helping engineers make an informed first-stage decision before validating the complete electrical limits and pin configuration.
ISL8491IP - 5V 5Mbps RS-485/RS-422 Transceiver | Renesas
The Renesas Electronics ISL8491IP is a 5 V, low-power RS-485/RS-422 line transceiver with one driver and one receiver, full-duplex operation, a maximum data rate of 5 Mbps, and a 14-pin PDIP package. The device combines differential RS-485 and RS-422 communication support in a single integrated circuit, making it suitable for industrial data links, instrumentation, and point-to-point balanced communication systems. An RS-485/RS-422 transceiver is an interface IC that converts logic-level signals into differential balanced signals for reliable data transmission over cables. These differential signaling methods are members of the broader interface-controller category, connect digital systems to physical communication links, and provide improved noise immunity compared with single-ended logic interconnects. The ISL8491IP supports both protocols, allowing equipment designers to select the appropriate termination and biasing arrangement for the cable and system topology. The verified part data identifies a 4.5 V to 5.5 V supply range, 5 Mbps maximum data rate, 70 mV receiver hysteresis, one transmitter, one receiver, full duplex, and an operating temperature range of -40°C to 85°C. These characteristics suit industrial equipment operating near a regulated 5 V rail and requiring communication speeds up to 5 Mbps. The through-hole PDIP-14 package is also appropriate for leaded PCB designs where a small surface-mount land pattern is not required. The ISL8491IP is listed as obsolete in the verified source data. Consequently, engineers should not assume that new production procurement is available and should confirm lifecycle status, traceability, and last-time-buy opportunities directly with the manufacturer or an authorized distributor. Renesas Electronics Corporation is the listed supplier, while the original documentation is associated with Intersil Corporation. Typical uses include industrial control links, factory automation equipment, remote sensor interfaces, RS-422 point-to-point links, and test-and-measurement systems. In these applications, the device separates the logic domain from the noisy cable environment through differential transmission and reception. Cable length, data rate, termination, common-mode range, and grounding remain system-level constraints that must be evaluated separately from the integrated circuit specifications. A practical design step is to preserve the transmitter enable and receiver enable control paths, place termination only where required by the cable topology, and provide a stable 5 V supply close to the device. Since the verified sources do not provide a complete pin table, absolute maximum ratings, output current, or detailed electrical characteristics, those values should be confirmed in the manufacturer datasheet before final release. This page combines verified distributor and datasheet information with lifecycle, sourcing, application, and design guidance. It also distinguishes verified facts from parameters that still require manufacturer-document confirmation, helping engineers evaluate the ISL8491IP without confusing an obsolete status with an interchangeable modern replacement.

Typical applications include routing audio signals in portable equipment, selecting sensor inputs in test and measurement systems, multiplexing communication channels, and switching low-voltage analog signals in battery-operated instruments. The 15 ns tON and 13 ns tOFF characteristics support fast system reconfiguration, while the low on-resistance limits signal attenuation across the selected channel. Designers should verify control-logic levels against the selected supply voltage and ensure that switched signals remain within the device's supported analog-signal range. The exposed thermal pad and exposed-pad construction also require a suitable PCB land pattern and adequate copper for heat spreading, particularly when continuously routing signals at higher frequencies or temperatures. This page consolidates the verified Renesas product information, source-linked pricing and lifecycle references, explicitly identified drop-in relationships, and practical selection guidance. It also separates documented performance from parameters that still require confirmation from the complete manufacturer datasheet or a specific distributor record.
ISL8499IRZ - Ultra-Low On-Resistance Quad SPDT Switch | Renesas
The Renesas ISL8499IRZ is a low-voltage, bidirectional quad SPDT analog switch, also described as a dual DPDT switch, designed for single-supply operation from +1.65 V to +4.5 V.

Typical uses include portable measurement equipment, battery-operated test instruments, analog signal conditioning, communication interfaces, and compact embedded systems. In these applications, the switch can select between external signals, route a signal toward an amplifier or converter, or isolate a measurement path during a test sequence. The low ON-resistance helps preserve signal amplitude, while the fast switching performance can reduce timing overhead in repeated routing operations. PCB implementation should follow the manufacturer pin and land-pattern guidance, paying particular attention to exposed-pad soldering and the control-logic levels. The 1.8 V-compatible control inputs allow operation from low-voltage digital systems, but the logic thresholds and supply sequencing must still be checked against the final system requirements. The short 3 x 3 mm package also requires careful placement of power and ground connections to minimize parasitic inductance and maintain clean analog signal behavior. This product page combines the manufacturer switching characteristics, package information, cross-reference guidance, and practical design considerations for engineers evaluating the ISL8499IRZ. It is intended to support footprint compatibility checks, signal-integrity planning, sourcing decisions, and early schematic and layout reviews.

Pricing shown below is referenced to the current verification date, while unverified details are explicitly marked for follow-up rather than inferred.
ISL8563CB - 2/2 RS-232 Transceiver, 250kbps | Renesas
The Renesas ISL8563CB is a 2/2 RS-232 transceiver IC with a 3 V to 5.5 V single supply, a guaranteed minimum data rate of 250 kbps, and 1 microamp low-power operation in an 18-pin SOIC package. It combines two transmitters and two receivers on one die, allowing a compact implementation of bidirectional serial-interface ports while meeting EIA/TIA-562 and EIA/TIA-232 specifications. An RS-232 transceiver is an interface IC that converts logic-level signals between a host or controller and a RS-232 physical link. The transmitter converts low-voltage digital signals into RS-232-level voltages, while the receiver converts the bipolar RS-232 input back into a logic-compatible signal. Within the broader hierarchy, this device is a line-driver and receiver interface IC used to bridge digital systems with RS-232 equipment. The ISL8563CB operates from a single +3 V to +5.5 V supply, including the lower-voltage condition identified in the verified datasheet description. Its low-power operation is specified at 1 microamp, making it relevant to portable and space-constrained systems where standby consumption matters. The guaranteed 250 kbps minimum data rate supports common serial-control, point-of-sale, industrial-interface, and legacy peripheral connections without requiring a separate high-speed transceiver. The device requires only four external 0.1 microfarad capacitors according to the verified manufacturer-datasheet description. This small external-component count simplifies layout and reduces the number of placement and routing decisions around the interface. Because the ISL8563CB integrates two transmitters and two receivers, each channel direction can be implemented without duplicating the driver or receiver function in separate packages. Typical uses include RS-232 links in personal digital assistants, palmtop computers, notebook and laptop computers, embedded control systems, and industrial data-acquisition equipment. The same device can also support service-console, configuration-port, and point-of-sale interfaces where an EIA/TIA-232-compatible physical layer is required but board area and standby power are constrained. Designers should verify signal levels, grounding, cable length, and system requirements against the manufacturer datasheet before replacing a discrete RS-232 implementation. The four external 0.1 microfarad capacitors should be placed close to their associated device pins, while supply and ground planes should provide a low-impedance return path. Because the verified data does not provide a complete 18-pin mapping, the package drawing and pin definitions must be checked against the datasheet before PCB release. This page consolidates the verified supply, speed, power, package, standard-compliance, pricing, and sourcing information for ISL8563CB and adds practical application guidance. It also explicitly distinguishes verified facts from parameters that remain unavailable in the supplied data, including detailed pin definitions, temperature limits, and confirmed drop-in substitute MPNs.

The device is designed for portable and embedded systems that require bidirectional serial communication using the RS-232 electrical interface. An RS-232 transceiver is an interface IC that converts logic-level transmit and receive signals into RS-232-compatible levels, then restores received RS-232 signals to logic levels for a host, controller, or peripheral. The ISL8563CP belongs to the interface IC category and combines two transmitters and two receivers in one package, providing bidirectional communication over two data channels. Its documented headline characteristics include operation from +3 V to +5.5 V, 1 µA operating supply current, and a maximum data rate of 250 kbps. The indexed datasheet states that the transmitters and receivers meet EIA/TIA-232 and EIA/TIA-562 specifications even when the supply voltage is 3.0 V. These characteristics suit equipment where low voltage compatibility and reduced supply demand are important. The ISL8563CP contains two complete transmit channels and two receive channels, allowing two simultaneous RS-232 links within one device. Unlike single-direction level-shifter blocks, this integrated arrangement reduces the component count required for a dual-port interface. Its 18-pin PDIP package is suitable for through-hole assembly and prototype or legacy system designs where a surface-mount package is unnecessary. Typical uses include RS-232 ports for personal digital assistants, palmtop computers, notebook and laptop computers, industrial control equipment, diagnostic interfaces, and embedded data-logging systems. A board designer can place the transceiver between a host UART and an external DB9 or other RS-232 connector, while observing the interface voltage, grounding, and protection requirements of the RS-232 environment. Designers should verify the logic levels, receiver thresholds, transmitter output levels, capacitance loading, and external protection requirements against the complete datasheet before production use. Because the verified results do not provide a complete pin table, exact pin names, temperature range, or recommended external network values, those details require confirmation from the original manufacturer documentation. The 1 µA operating-current figure should also be understood under its stated test conditions rather than assumed across every operating mode. This page consolidates the verified distributor indexing, package information, interface standards, operating limits, and application guidance for the ISL8563CP. It also distinguishes confirmed technical facts from unavailable details and avoids presenting unverified drop-in equivalents or fabricated pricing as authoritative purchasing data.
ISL8563IB - 250kbps RS-232/RS-562 Transceiver | Renesas Electronics
The Renesas Electronics ISL8563IB is a 2-transmitter, 2-receiver RS-232 and RS-562 interface transceiver operating from a 3V to 5.5V supply at up to 250kbps, housed in an 18-pin SOIC package. The device provides approximately 1µA low-power operation and incorporates ESD protection rated at ±15kV, making it suited to compact battery-powered and portable serial interfaces. It is used for RS-232 and RS-562 data links in notebook computers, PDAs, palmtop computers, digital cameras, and other portable equipment. An RS-232 transceiver is an interface IC that combines voltage-level transmitters and receivers for unbalanced serial communication. It belongs to the driver, receiver, and transceiver hierarchy within interface ICs, converting logic-level signals into RS-232-compatible levels and reconstructing received logic signals. The RS-562 standard is referenced alongside EIA/TIA-232 and EIA/TIA-562, allowing the ISL8563 family to support both communication approaches where compatible with the system interface requirements. The ISL8563IB provides two transmit channels and two receive channels, supporting a complete dual-direction serial interface in one package. Its maximum data rate of 250kbps accommodates higher-speed legacy serial links, while the 3V to 5.5V supply range supports both 3V and 5V system rails. The approximately 1µA operating-current figure is particularly relevant to portable equipment where standby and overall battery consumption constrain the usable architecture. ESD protection of ±15kV strengthens the device against electrostatic discharge encountered during connector handling and field use. The 18-pin SOIC package also provides a conventional surface-mount option for RS-232 ports. Because the available verification data does not include the complete electrical tables, exact output levels, slew rates, receiver thresholds, and internal charge-pump details, designers should consult the manufacturer datasheet before finalizing timing, capacitance, and signal-integrity margins. Typical uses include serial ports in portable computers, PDAs, palmtop computers, digital cameras, battery-operated instruments, and other equipment requiring an RS-232 or RS-562 connection. In a portable design, the 3V-to-5.5V operating range permits connection to either rail, while the low 1µA operating-current characteristic supports power-conscious operation. Designers should still confirm whether the cited value applies to a specific mode or test condition in the datasheet. The primary design consideration is preserving adequate driver, receiver, and connector margins under the actual cable and load conditions. Place the transceiver close to the interface connector, provide the required bypass capacitance, observe the maximum supply voltage of 5.5V, and validate the complete channel with the intended cable length and baud rate. The available data does not provide a verified pin-by-pin mapping, so the package drawing and pin descriptions should be taken directly from the manufacturer datasheet. This product record consolidates the verified distributor specifications, package information, commercial availability, and practical selection considerations for the ISL8563IB. It also distinguishes verified facts from parameters that still require datasheet confirmation and explains why no unverified cross-brand substitute is presented as a guaranteed drop-in replacement.
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.

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.

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.

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.

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

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.

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.

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.

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.
