The Renesas Electronics ISL8499IV is an ultra-low ON-resistance, bidirectional Quad SPDT analog switch, also described as a dual DPDT switch, for single-supply operation from +1.65 V to +4.5 V. The device is supplied in a 16-TSSOP package and is intended for low-voltage signal-routing applications, including battery-powered equipment. Its listed ON resistance is approximately 250 mOhm in distributor product data, while the manufacturer-oriented description identifies 0.24 Ohm ON resistance at a +4.3 V supply and 0.26 Ohm at +3.0 V. The switch also provides fast switching behavior, with tON and tOFF values reported in the Intersil datasheet excerpt as 15 ns and 13 ns respectively. Digital logic inputs are described as 1.8 V logic-compatible when the device is operated from a single +3 V supply. The ISL8499IV is a bidirectional analog switch, so its signal paths can be routed in either direction, making it suitable for multiplexed sensor, measurement, communication, and low-voltage analog systems. It is identified by Renesas as a pin-compatible drop-in replacement for the STG3699 and DG2799, according to the supplied cross-reference material. This page combines manufacturer identification, distributor specifications, cross-reference information, practical design notes, and a parameter comparison to support sourcing and engineering decisions. 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.
ISL8563CP - 250kbps RS-232 Transceiver | Renesas
Renesas ISL8563CP is a dual RS-232 transmitter and receiver interface IC operating from +3 V to +5.5 V at data rates up to 250 kbps, with a low operating supply current of 1 µA and an 18-pin PDIP package. 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. 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.
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.
ISO1042DWVR - 5 Mbps Reinforced Isolated CAN | Texas Instruments (Tape & Reel)
The Texas Instruments ISO1042DWVR 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.

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.
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 Texas Instruments ISO1211DR 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.

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.
ISO1410BDWR - 500kbps Isolated RS-485/RS-422 | Texas Instruments (Tape & Reel)
The Texas Instruments ISO1410BDWR 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 ISO1410BDWR 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 ISO1410BDWR.
ISO1410DW - 500Kbps 5kVrms Isolated RS-485 | Texas Instruments
The Texas Instruments ISO1410DW is an EMC-protected, half-duplex RS-485 and RS-422 transceiver rated for 500 Kbps operation and 5 kVrms galvanic isolation. The device is packaged in a 16-pin wide-body SOIC with Texas Instruments package code DW and supports an operating temperature range of -40°C to +125°C. It provides one transceiver per package and is intended for industrial communication links exposed to electrostatic discharge, electrical fast transients, and other electromagnetic disturbances. An isolated RS-485/RS-422 transceiver is an interface IC that converts logic-level signals into differential bus signals and receives differential bus signals back into logic-level outputs. Galvanic isolation places a reinforced isolation barrier between the bus-facing side and the logic side of the device. Within the product hierarchy, the ISO1410DW is a differential line transceiver, an interface IC, and a semiconductor designed for industrial networking and control systems. The ISO1410DW's principal verified features include a maximum signaling rate of 500 Kbps, 5 kVrms isolation, half-duplex operation, RS-485 and RS-422 support, and robust EMC protection. Its 16-pin DW SOIC package provides sufficient pin count for the isolated transceiver interface, supply connections, bus terminals, and enable-related functions. The wide -40°C to +125°C temperature range makes it suitable for industrial equipment subjected to extended thermal conditions. Texas Instruments describes the ISO14xx family as galvanically isolated differential line transceivers for TIA/EIA RS-485 and RS-422 applications. These noise-immune devices are designed for harsh industrial environments, and their bus pins are intended to withstand high levels of IEC electrostatic-discharge and electrical-fast-transient events. The manufacturer also provides the ISO1410DWEVM evaluation module for evaluating the ISO1410 in its 16-pin wide-body SOIC package. Typical uses include isolated industrial bus links, factory automation equipment, building-control gateways, industrial sensors, and communication interfaces located at a significant ground-potential difference from the host controller. In these systems, the transceiver provides the physical-layer connection between a logic-side controller and a differential RS-485 or RS-422 bus. Half-duplex operation allows a shared pair of conductors to carry data in both directions, but bus direction must be managed by the host interface. Designers should confirm the complete pinout, isolation requirements, bus termination strategy, fail-safe behavior, and external interface voltage levels against the manufacturer datasheet before layout. A 16-pin wide-body SOIC footprint should not be mixed with a narrow-body SOIC footprint, and the isolation barrier placement should follow the manufacturer's recommended layout and creepage guidance. This page consolidates verified manufacturer and distributor information for ISO1410DW, including commercial availability, package details, application guidance, and a conservative drop-in replacement assessment. It also separates confirmed specifications from fields that require confirmation from the complete datasheet, helping engineers shorten component research without obscuring uncertainty.
ISO1410DWR - 500kbps Isolated RS-485/RS-422 | Texas Instruments
The Texas Instruments ISO1410DWR is an EMC-protected, galvanically isolated half-duplex RS-485 and RS-422 transceiver with a maximum signaling rate of 500 kbps, 5-kVrms isolation protection, and a 16-pin wide-body SOIC package. The device operates across a -40 °C to +125 °C temperature range and includes a fail-safe circuit for dependable bus behavior. An isolated RS-485/RS-422 transceiver is a digital interface IC that combines differential line-driver and receiver functions with a signal-isolation barrier. It belongs to the interface-IC hierarchy: RS-485/RS-422 transceiver > isolated transceiver > digital interface IC > semiconductor. Galvanic isolation separates the bus-side and logic-side circuits, helping protect equipment from ground-potential differences and industrial transients while allowing reliable communication over long cable runs. The ISO1410 family is designed for harsh industrial environments. Its bus pins are specified to withstand high levels of IEC electrostatic-discharge and electrical-fast-transient events, reducing the need for additional external protection in suitable designs. The robust EMC characteristics make the device useful in industrial automation, factory equipment, building controls, instrumentation, and other systems where the communication bus is exposed to electrical noise. The ISO1410 supports up to 500 kbps signaling, making it appropriate for moderate-speed half-duplex RS-485 networks rather than high-speed data-center or automation links. Its isolated architecture allows the transceiver to bridge a field-side bus and a host-side digital interface while preventing ground currents from flowing through the communication path. The 16-pin SOIC (DW) package supports conventional surface-mount assembly and is identified by the ISO1410DWR ordering code. Typical applications include industrial motor controllers, PLC interfaces, remote sensor networks, industrial gateways, building automation controllers, and RS-422 equipment connections. For these applications, the combination of half-duplex operation, 500-kbps signaling, fail-safe behavior, EMC protection, and 5-kVrms isolation helps simplify the physical layer while improving robustness against industrial electrical stress. Designers should verify the complete datasheet for pin assignments, isolation ratings, bus termination requirements, recommended network topology, and operating constraints before releasing a PCB. The verified source data confirms the device family, package, speed, isolation, temperature range, and EMC protection, but detailed pin-level and electrical-limit information is not included in the supplied records. This page combines verified product attributes, sourcing information, comparison guidance, and practical engineering cautions for faster component evaluation.
ISO1412BDW - 500kbps Isolated RS-485/RS-422 | Texas Instruments
Texas Instruments ISO1412BDW is an EMC-protected, 500-kbps, full-duplex isolated RS-485 and RS-422 transceiver with 5-kVrms reinforced isolation in a 16-pin SOIC package. The device supports single-side powered isolation, industrial temperature operation from -40°C to +125°C, and a robust EMC protection network for long-distance differential data links. Its isolated transceiver architecture places a galvanic barrier between the bus-facing interface and the logic-side interface, helping protect host circuitry from ground-potential differences and electrical transients. An isolated RS-485/RS-422 transceiver is a communication interface that combines differential line drivers, differential receivers, and electrical isolation within one integrated circuit. In the broader hierarchy, it belongs to interface ICs and bus transceivers. RS-485 supports multipoint, half-duplex buses in many installations, while RS-422 commonly supports point-to-point, full-duplex links. The ISO1412BDW supports both standards and provides 500-kbps operation for industrial communication, factory automation, building controls, and equipment networks. Key features include 500-kbps signaling speed, full-duplex operation, 5-kVrms isolation, EMC protection, and operation from -40°C to +125°C. The 16-SOIC package provides a practical surface-mount option for industrial control boards. The ISO1412BDW is identified as RoHS compliant by distributor data, and its operating-temperature range supports use across demanding commercial and industrial environments. Exact supply-voltage, receiver-threshold, propagation-delay, and bus-loading limits should be confirmed in the manufacturer datasheet. The ISO1412BDW is designed for bidirectional differential data transfer across an isolation barrier. Full-duplex capability permits separate transmit and receive paths, which is useful when a system cannot switch a shared half-duplex bus. The integrated protection and isolation functions reduce the amount of external surge and isolation circuitry required, but correct layout, decoupling, bus termination, and common-mode considerations remain essential for reliable field communication. Typical uses include industrial PLC and factory-automation links, isolated instrumentation, building-automation equipment, long-reach RS-485 or RS-422 nodes, and industrial gateways that must bridge a noisy bus to a host controller. The 500-kbps rate is suitable for supervisory data, configuration traffic, and moderate-speed industrial messages rather than high-bandwidth streaming. Design the isolation barrier and bus interface on the PCB with the manufacturer's isolation and layout guidance. Keep bus-side and logic-side copper, components, and ground systems separated, place decoupling capacitors at the appropriate supply pins, and apply termination only where signal-integrity analysis requires it. The isolation rating and EMC claims must be evaluated for the final enclosure, cable, grounding, and surge environment. This page consolidates the verified manufacturer and distributor information for the ISO1412BDW, distinguishes confirmed characteristics from parameters requiring datasheet review, and provides application and selection guidance that is not available from a distributor listing alone.

ISO1430DW - 12Mbps Isolated RS-485/422 | Texas Instruments
Texas Instruments ISO1430DW is an EMC-protected, half-duplex isolated RS-485 and RS-422 transceiver operating at up to 12 Mbps and providing 5 kVrms reinforced isolation in a 16-pin SOIC package. It is designed for industrial communication links where galvanic isolation, surge withstand, and reliable differential signaling are required. An isolated transceiver is an interface IC that transfers data across a galvanic barrier while electrically separating the bus-side and logic-side circuits. The ISO1430 belongs to the isolated differential transceiver hierarchy, combining an RS-485/RS-422 interface, signal isolation, and electromagnetic-interference protection. This isolation helps prevent ground-potential differences, fault energy, and common-mode disturbances from reaching the host electronics. The primary specifications establish its industrial suitability: 12 Mbps maximum data rate, 5 kVrms isolation, half-duplex operation, support for both RS-485 and RS-422, and an operating temperature range of -40 °C to +125 °C. The 16-SOIC package supports surface-mount assembly, while the listed 3-7 business-day lead time provides useful procurement context. The device is identified as RoHS compliant and active. The ISO1430DW is intended for harsh industrial environments where bus pins may encounter electrostatic-discharge and electrical-fast-transient events. Its EMC protection is a key functional attribute rather than merely a compliance label. The half-duplex architecture supports shared differential buses and reduces the number of physical data paths required when transmit and receive operations occur on the same pair of wires. Typical uses include industrial automation equipment, factory-floor controllers, building-automation interfaces, motor-control systems, and industrial communications links operating at distances where noise immunity and isolation are important. The RS-422 capability also allows point-to-point or multidrop differential communication arrangements where appropriate termination and biasing are used. Designers should place protection, termination, and isolation-layout elements according to the manufacturer datasheet and the selected bus topology. Cable length, transceiver data rate, connector design, grounding strategy, and external surge-protection requirements must be evaluated together; the 12-Mbps figure does not guarantee the same usable distance at every data rate. This product page consolidates verified manufacturer and distributor information, practical application guidance, procurement details, and a conservative drop-in comparison. It also distinguishes verified alternatives from package-only or functionally similar parts that would require additional engineering review.
ISO1430DWR - 12Mbps Isolated RS-485 Transceiver | TI
The Texas Instruments ISO1430DWR is an EMC-protected, half-duplex, galvanically isolated RS-485 and RS-422 transceiver supporting data rates up to 12 Mbps, with 5-kVrms reinforced isolation in a 16-pin SOIC (DW) package. It is designed to protect industrial equipment from electrostatic-discharge and electrical-fast-transient disturbances encountered on field-bus wiring. An isolated RS-485/RS-422 transceiver is a differential interface IC that combines a line driver, line receiver, and galvanic isolation barrier. The isolation barrier separates the equipment-side ground domain from the noisy communications bus, reducing common-mode current paths and preventing ground-potential differences from disrupting data transfer. Within the interface hierarchy, the ISO1430 belongs to the RS-485/RS-422 transceiver class and the broader isolated communications interface category. Key features include a 12-Mbps maximum data rate, half-duplex operation, one driver and one receiver, 5-kVrms isolation, EMC protection, and an operating-temperature range of -40°C to +125°C. These characteristics suit factory automation, grid infrastructure, photovoltaic inverters, industrial motor drives, HVAC equipment, building automation, and fieldbus gateways where long cable runs and electrically noisy environments are common. The ISO14xx device family uses differential signaling to reject common-mode noise and support robust point-to-point or multidrop communications. Its integrated isolation prevents the bus-side ground from being directly connected to the logic-side ground, while its EMC protection helps the transceiver withstand connector-side ESD and EFT events. The 12-Mbps ceiling provides ample bandwidth for high-speed industrial control data while preserving compatibility with established RS-485 and RS-422 networks. Typical deployments include PLC-to-RS-485 fieldbus links, photovoltaic-inverter monitoring, grid-control equipment, industrial motor controllers, remote sensor gateways, and HVAC or building-automation controllers. A one-transceiver arrangement supports half-duplex buses where the same differential pair carries both transmitted and received data through controlled driver-enable timing. Designers should carefully separate logic-side and bus-side ground domains, provide the decoupling and isolation components specified by the Texas Instruments manufacturer datasheet, and maintain controlled-impedance routing between the transceiver and external connectors. PCB creepage, isolation-barrier placement, bus termination, protection grounding, and common-mode-transient requirements should be reviewed before production release. This page consolidates verified manufacturer and distributor information, parameter-level comparisons, qualified drop-in alternatives, application guidance, and practical PCB considerations. It highlights the trade-offs among speed, isolation rating, bus directionality, and package compatibility to support faster engineering selection and sourcing decisions.
ISO1450BDW - 50Mbps 5kVrms RS-485/422 Isolated Transceiver | TI
The Texas Instruments ISO1450BDW is an EMC-protected, galvanically-isolated, half-duplex RS-485 and RS-422 transceiver housed in a 16-pin wide-body SOIC (DW) package with 5 kVrms reinforced isolation. The device operates at data rates up to 50 Mbps and supports TIA/EIA-485-A and TIA/EIA-422-B standards, integrating a differential line driver, a differential line receiver, a power transformer driver, and an LDO regulator on the isolated side into a single silicon die. An isolated RS-485 transceiver is a physical-layer interface IC that combines a galvanic isolation barrier (typically using an on-chip silicon-oxide or polyimide-based capacitive isolator plus an embedded micro-transformer for power transfer) with a differential line transceiver. The isolation barrier breaks ground loops between the fieldbus wiring and the controller side, providing safety in high-voltage environments and immunity to common-mode transients. In the system hierarchy, ISO1450BDW sits at the physical layer (OSI layer 1) of industrial fieldbus, motor-drive, and substation networks, between the bus cable and a UART or serial-communications controller (e.g., an MCU USART, FPGA LVDS, or DSP SCIA). Key differentiating features of the ISO1450BDW include integrated digital isolation that eliminates the need for a separate digital isolator and isolated DC-DC converter, basic and reinforced insulation ratings per VDE 0884-11, working voltage of 1060 Vrms and surge isolation voltage of 10 kVpk, plus robust bus-side protection against IEC 61000-4-2 electrostatic discharge and IEC 61000-4-4 electrical fast transients. The device also provides thermal shutdown, current limiting, and fail-safe receiver outputs when the bus is idle, shorted, or terminated but undriven. Architecturally, the ISO1450BDW uses TI's silicon dioxide capacitive-isolation technology with an embedded center-tapped transformer for primary-to-secondary power transfer, removing the requirement for an external isolated supply on the bus side. The wide-body SOIC (DW) package maintains the >8mm clearance and creepage distances required for reinforced insulation under IEC 60747-17 and UL 1577, while offering a familiar SOIC-16 footprint that simplifies board layout. Typical applications include factory-automation fieldbus links (Profibus, Modbus RTU, BACnet MS/TP), solar inverter RS-485 monitoring strings, motor-drive control and feedback links, and any industrial-controller UART-to-RS-485 path where robust EMC performance and galvanic isolation are mandatory. Design considerations include placing 220 nF 0603 bypass capacitors on each VCC pin near the device, observing the 50 Mbps data-rate limit when using non-shielded twisted-pair cable, and respecting the maximum bus loading of 32 unit loads. This page synthesizes distributor pricing, drop-in same-brand alternatives, and EMC-aware design notes not always consolidated on a single manufacturer page.
ISO1450BDWR - 50Mbps 5kVrms Isolated RS-485/RS-422 Transceiver | Texas Instruments
The Texas Instruments ISO1450BDWR is a galvanically isolated, EMC-protected, 50-Mbps half-duplex RS-485/RS-422 transceiver housed in a 16-pin SOIC (DW) package with wide-body creepage and clearance for 5 kVrms reinforced isolation. The device integrates a single differential line driver/receiver pair, an on-chip low-dropout isolated DC-DC bias supply, and TI's silicon-dioxide (SiO2) capacitive isolation barrier. An isolated RS-485/RS-422 transceiver is a transceiver that bridges a logic-level UART or SPI controller across an isolation barrier to a differential bus that conforms to TIA/EIA-485-A or TIA/EIA-422. The isolation galvanically separates the field-side bus (which can be exposed to high common-mode voltages, ground loops, or surge events) from the low-voltage logic domain. In the broader hierarchy, the ISO1450 belongs to isolated interface ICs, which sit under interface ICs, which in turn fall under integrated circuits used for industrial communication links. Key features include ±16 kV IEC 61000-4-2 ESD (HBM-equivalent on bus pins), ±4 kV IEC 61000-4-4 EFT immunity, 50 Mbps NRZ signaling, 1/8 unit-load support for up to 256 nodes on the bus, an extended -40C to +125C operating range, thermal shutdown, current limiting, and a low-power standby mode. The 5 kVrms reinforced isolation rating eliminates external optocouplers and isolated bias supplies, cutting BOM count and PCB area. The architecture pairs a TI proprietary differential line driver with a capacitive isolation channel that carries both data and bias power. The integrated isolated DC-DC eliminates the need for a separate isolated bias supply; only a single 3.3V or 5V rail on VCC1 is required to operate the field-side bus driver across the barrier. Typical applications include isolated RS-485 nodes in industrial fieldbus networks (Modbus RTU, PROFIBUS), solar inverter string monitoring, battery management system (BMS) slave communications, and any system where high common-mode transients appear across the bus-ground reference. When designing with the ISO1450BDWR, place 100 nF decoupling capacitors on both VCC1 and VCC2 within 2 mm of the device pins, and keep the SOIC-16 wide-body (DW) land pattern intact to preserve the 5 kVrms creepage. For best EMC, add a 100 ohm differential termination at the bus end and a TVS diode such as the SMBJ12CA if the cable runs outdoors. This page synthesizes distributor pricing, drop-in alternatives drawn from the same ISO14xx family and competitor cross-references, and practical EMC layout notes not consolidated in the manufacturer datasheet.
ISO1450DW - 50 Mbps 5 kVrms Isolated RS-485/RS-422 | Texas Instruments
Texas Instruments ISO1450DW is an EMC-protected, 50-Mbps, half-duplex, 5-kVrms isolated RS-485 and RS-422 transceiver in a 16-pin SOIC wide-body package. It is designed for industrial communication links that require galvanic isolation, robust electromagnetic-noise immunity, and high-speed differential signaling. The verified manufacturer information identifies the ISO1450 family as an isolated differential line transceiver for TIA/EIA RS-485 and RS-422 applications, while distributor data identifies ISO1450DW as a 1/1 transceiver with a 16-SOIC package. The device operates from 1.71 V to 5.5 V and is specified for operation from -40 °C to 125 °C, providing a useful combination of low-voltage digital compatibility and extended industrial temperature coverage. Its 5-kVrms isolation rating is intended to help protect logic-side equipment from high-energy bus-side transients and ground-potential hazards, while the EMC protection is intended to improve operation in electrically noisy industrial environments. The 50-Mbps signaling capability supports high-speed half-duplex point-to-point or multipoint bus communication where system topology and termination are properly controlled. In the ISO1450 family, ISO1450DW is the wide-body 16-pin SOIC ordering option; package code DW identifies that mechanical outline, and the ISO1410DWEVM is identified as the evaluation module for evaluating the related isolated RS-485 ISO1410 in the same DW package family. ISO1450DW is therefore appropriate for factory automation, industrial controllers, test equipment, building systems, and communication interfaces where isolation and noise robustness are more important than a low-cost non-isolated transceiver. The half-duplex arrangement means transmit and receive functions share the differential bus pins, so firmware and bus direction control must be managed carefully. Designers should also verify the complete isolation system, cable length, termination, grounding, and protection-network strategy against their application requirements.
ISO1450DWR - 50Mbps Isolated RS-485/422 | Texas Instruments
The Texas Instruments ISO1450DWR is an EMC-protected, 50-Mbps, half-duplex isolated RS-485 and RS-422 transceiver packaged in a 16-pin SOIC (DW). It combines differential bus-driver and receiver functions with 5-kVrms galvanic isolation, making it suitable for industrial systems where communication lines cross high-potential barriers or encounter substantial electromagnetic interference. An isolated RS-485 or RS-422 transceiver is an interface IC that transfers differential data across a bus while electrically separating the logic-side circuitry from the cable-side circuitry. The isolation barrier helps protect low-voltage host electronics from ground-potential differences, surge energy, and industrial noise. Within the hierarchy of interface semiconductors, the ISO1450 is a differential line transceiver, a digital isolator, and ultimately a network and industrial communication interface IC. The ISO1450DWR supports a maximum data rate of 50 Mbps in half-duplex operation. Its EMC protection is intended to help bus pins withstand electrostatic-discharge and electrical-fast-transient events encountered in harsh industrial environments. The 5-kVrms isolation rating is the central safety feature for factory automation, grid infrastructure, motor drives, and building-control systems. Operation from -40°C to +125°C supports a broad range of industrial temperature conditions. The 16-pin SOIC (DW) package provides a conventional surface-mount footprint suitable for high-volume PCB assembly. Because the transceiver is half-duplex, driver and receiver paths share the bus connection, and the system must control transmit and receive states without contention. Isolation also requires careful treatment of bus-side supply voltage, ground, and printed-circuit-board creepage rather than treating the isolation barrier as a decorative layout feature. Typical uses include isolated RS-485 links in PLC systems, photovoltaic inverters, HVAC controllers, industrial gateways, motor-control equipment, and building-automation nodes. Its 50-Mbps capability is useful for factory protocols, while 5-kVrms isolation supports applications where ground offsets or transient events could damage unprotected host circuitry. Designers should verify the complete pin assignment and isolation-component requirements in the manufacturer datasheet. PCB layout should preserve isolation creepage and clearance, route bus traces away from sensitive logic, use suitable protection networks where the application requires them, and provide correctly decoupled isolated-side supplies. The verified source data does not provide the complete pin table, pricing, electrical thresholds, or lifecycle details needed to substitute assumptions. This page consolidates verified manufacturer and distributor information with practical selection, layout, and comparison guidance. It distinguishes confirmed ISO1450DWR specifications from parameters that still require datasheet or quotation confirmation, helping engineers evaluate the 50-Mbps, 5-kVrms isolated interface without treating incomplete cross-reference information as a guaranteed drop-in replacement.
