ISL8563IP

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.

ISLA212P20IRZ

ISLA212P20IRZ - 12-Bit 200MSPS SAR ADC, 72-QFN | Renesas

The Renesas (formerly Intersil) ISLA212P20IRZ is a 12-bit, 200 MSPS successive-approximation-register (SAR) analog-to-digital converter that delivers high dynamic performance at low power. It is part of the pin-compatible ISLA212P family built on Intersil's proprietary FemtoCharge™ technology on a standard CMOS process, allowing sampling rates up to 250 MSPS, 200 MSPS, and 130 MSPS variants from a single 72-contact QFN (10 mm x 10 mm) footprint with an exposed thermal paddle. What is a SAR ADC? A successive-approximation-register analog-to-digital converter is a sampling converter that uses a binary-search algorithm against a precision DAC to resolve the input voltage one bit per clock cycle. SAR ADCs sit in the data-converter hierarchy as ADC -> Nyquist/oversampling ADC -> mixed-signal IC -> semiconductor. They offer excellent linearity, deterministic latency, and low power compared to flash or pipeline converters at moderate sample rates, making them well-suited to instrumentation, communications baseband, and wideband test equipment. Key headline specifications of the ISLA212P20IRZ include 12-bit resolution, 200 MSPS sampling rate, LVDS/CMOS-selectable digital outputs, SPI configuration port, and -40 °C to +85 °C industrial operating range. The device supports both single-data-rate (full-width SDR) and double-data-rate (half-width DDR) output modes, giving system designers flexibility for FPGA, ASIC, or DSP capture. A 72-contact QFN package with an exposed paddle supplies a low thermal-resistance path for high-clock full-rate operation. Architecturally, the part uses FemtoCharge™ switched-capacitor input sampling and an internal high-precision reference, with optional external reference support. Its pipeline-style latency is deterministic and pipelined-friendly, simplifying FPGA capture at multi-hundred-megasample rates. Gain, offset, and output timing are adjustable through the SPI port, supporting per-channel calibration in multi-board systems. Typical applications for the ISLA212P20IRZ include wideband test and measurement instruments, radar IF/baseband digitizers, communications receiver baseband I/Q capture, medical imaging front-ends, and high-channel-count data-acquisition systems. The combination of 12-bit resolution, 200 MSPS throughput, and low power suits portable and ruggedized platforms where thermal density must be controlled. Designers should provide adequate ground and decoupling on the analog and digital rails, follow the exposed-paddle soldering recommendations (see manufacturer application layout), and verify SPI configuration timing during bring-up. When migrating between family members, no PCB rework is required. This page synthesizes distributor pricing, validated drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet header alone.

ISLA214P12IRZ - 14-Bit 125MSPS SAR ADC | Renesas Electronics
ISLA214P12IRZ

ISLA214P12IRZ - 14-Bit 125MSPS SAR ADC | Renesas Electronics

The Renesas Electronics (formerly Intersil) ISLA214P12IRZ is a 14-bit, 125 MSPS successive-approximation-register (SAR) analog-to-digital converter delivering very high dynamic range and low power consumption, packaged in a 72-pin QFN (10x10 mm). The part offers 1 differential input channel with unbuffered (switched-capacitor) analog inputs and is part of a pin-compatible family of 12- to 16-bit ADCs with sample rates from 125 MSPS to 500 MSPS, allowing a single PCB layout to migrate across resolution and speed grades. A SAR ADC is a type of analog-to-digital converter that uses a binary-search algorithm implemented with a capacitive DAC and a high-speed comparator to resolve each conversion in N clock cycles for N-bit resolution. SAR ADCs are valued for their deterministic latency, single-shot accuracy, and excellent dynamic performance, and they sit at the leaf of the broader data-converter hierarchy: SAR ADC -> A/D converter -> data acquisition IC -> signal chain -> mixed-signal semiconductor. The ISLA214P12 uses a high-performance, low-power core that is well suited for instrumentation, communications and imaging front ends where both speed and DC accuracy matter. Key differentiating features include 125 MSPS maximum sampling rate, 14-bit resolution, 1.8 V/3.3 V supply operation, LVDS/LVCMOS-compatible digital outputs, and an internal reference. The 72-QFN (10x10) package provides a low thermal-resistance path and is footprint-compatible with the wider ISLA214P/ISLA216P/ISLA214S/ISLA216S family, so a single PCB layout can be reused across multiple performance tiers. The device also integrates an input common-mode clamp and a self-calibrating background circuit that maintains DC accuracy over temperature. The pin-compatible family approach means a system designed around the ISLA214P12IRZ can be re-populated with ISLA214P25, ISLA214P50 or higher-resolution members (ISLA216P25/ISLA216P50) when additional sample rate or resolution is required, with no PCB changes. This is particularly valuable for multi-product platforms where one design must address multiple market tiers. Typical applications include communications test equipment, radar and signal-intelligence front ends, medical imaging (ultrasound beamformers), high-speed data acquisition cards, and industrial imaging. Designers favor the ISLA214P12IRZ when very high dynamic range, low latency and pin-compatible scalability across the ISLA214P/ISLA216P family are required within a 72-QFN footprint. When designing with this converter, pay close attention to the analog-input network: a wide-band, low-distortion differential driver (such as the ISL552xx or ADA4937 family) must present the proper common-mode voltage and source impedance to the unbuffered switched-capacitor inputs. Decouple each supply pin individually with 100 nF ceramic capacitors placed as close as possible to the package, and provide a solid ground plane under the exposed pad to minimize digital switching noise coupling into the analog front end. This page synthesizes distributor pricing, drop-in same-brand and cross-brand alternatives, and practical design notes (clock, input network, decoupling, exposed-pad soldering) not found in a single place in the manufacturer datasheet, giving engineers a faster starting point for ISLA214P12IRZ-based designs.

ISLA214P25IRZ - 14-Bit 250MSPS ADC, 72-QFN | Renesas
ISLA214P25IRZ

ISLA214P25IRZ - 14-Bit 250MSPS ADC, 72-QFN | Renesas

The Renesas ISLA214P25IRZ is a 14-bit, 250 MSPS low-power high-performance analog-to-digital converter (ADC) with one input channel, housed in a 72-contact QFN (10x10 mm) package with an exposed thermal paddle. It uses Renesas' proprietary FemtoCharge™ switched-capacitor technology on a standard CMOS process to deliver high dynamic performance at sample rates up to 250 MSPS, and operates from a single 1.8 V supply over the -40 °C to +85 °C industrial temperature range. An ADC (analog-to-digital converter) is a data-conversion integrated circuit that quantizes a continuous-time analog input signal into a discrete digital code at a specified sampling rate. High-speed pipeline ADCs such as the ISLA214P25IRZ sit in the signal chain between the analog front end (amplifier / filter / driver) and a downstream FPGA, ASIC, or DSP, where they convert wideband IF or baseband signals into digital words. The ISLA214P25IRZ occupies the "ADC -> data converter IC -> data acquisition -> signal chain IC" hypernym in the power-management and mixed-signal taxonomy and is widely used in communications, defense electronics, and test-and-meeasurement equipment. Key specifications include 14-bit resolution, 250 MSPS maximum sampling rate, SPI/serial configuration interface, selectable LVDS or CMOS digital outputs configurable as full-width single-data-rate (SDR) or half-width double-data-rate (DDR), and a 72-lead QFN-EP (10x10 mm) package. The converter is part of a pin-compatible 12-bit to 16-bit Renesas FemtoCharge™ ADC family that scales from 130 MSPS to 500 MSPS, simplifying board-level migration. A serial peripheral interface (SPI) port provides extensive configurability, including fine control of gain and offset. Architecturally, the part uses a multi-stage pipeline core that is interleaved with on-chip calibration logic; FemtoCharge™ technology reduces the reset-noise kick usually associated with switched-capacitor gain stages, improving SFDR and SNR at high input frequencies. Digital output data can be routed through a flexible LVDS/CMOS interface, allowing the same device to drive an FPGA in SDR (1 data line per channel) or DDR (½-width) mode, which simplifies board-level data capture at multi-hundred-megasample rates. Typical applications include communications receivers (LTE, WiMAX, multi-carrier GSM/EDGE base stations), radar and EW systems, medical imaging, high-speed data acquisition cards, and bench-top instrumentation. The wide input bandwidth and configurable digital interface make it equally suited to single-channel IF sampling and to multi-channel diversity receiver sub-systems. According to the Renesas datasheet FN6510, the device is part of a larger pin-compatible family so customers can re-use the same PCB footprint to scale resolution (12/14/16 bit) and sample rate (130/200/250 MSPS) as system requirements evolve. A key design consideration is power-supply decoupling and LVDS-termination strategy: each LVDS output pair must be DC-terminated with a 100 Ω differential resistor at the FPGA receiver, and a low-noise LDO (e.g. a TPS7A47-class part) should power the AVDD rail. Designers should also confirm that the FPGA IDDR/ISERDES block supports the selected SDR/DDR mode and that the input drive amplifier meets the part's 1.5 V p-p full-scale input requirement with adequate linearity at the highest input frequency of interest.

ISLA216S13IR1Z

ISLA216S13IR1Z - 16-Bit 130MSPS JESD204B ADC | Renesas

The Renesas ISLA216S13IR1Z is a 16-bit, 130 MSPS analog-to-digital converter with a JESD204B-compliant high-speed serial output, housed in a 48-pin QFN (7x7 mm) package. Designed on Intersil's proprietary FemtoCharge technology in a standard CMOS process, this SAR-pipelined ADC delivers low-power, high-performance conversion suitable for communications, instrumentation, and defense signal chains. The serial interface reaches up to 4.375 Gbps per lane and uses two lanes in this 16-bit, single-channel configuration. An analog-to-digital converter (ADC) is an integrated circuit that converts continuous analog signals into discrete digital codes, forming the critical boundary between the analog and digital domains in mixed-signal systems. ADC architectures include SAR (successive approximation register), pipelined, sigma-delta, and flash; the ISLA216S family uses a pipelined architecture with SAR-style backend, which balances high sampling speed with multi-MHz analog input bandwidth. The 16-bit class sits at the upper end of resolution for high-speed converters, enabling very low quantization noise floor. Key features of the ISLA216S13IR1Z include 130 MSPS sampling rate (with up to 250 MSPS and 500 MSPS speed grades available in the same family), 16-bit resolution, 1 input channel, JESD204B serial output with deterministic latency, and pin compatibility with 12-bit and 14-bit family members (ISLA212S, ISLA214S). The device supports configurable packing modes and offers multi-chip time alignment via the JESD204B subclass-1 features. Operating temperature spans -40 C to +85 C (industrial grade), with the R1Z suffix denoting the tape-and-reel packaging option. From a digital-system perspective, the JESD204B serial link eliminates the wide parallel CMOS/ LVDS data bus that traditionally constrained high-speed ADC board layout, instead using a serialized link that greatly reduces board-routing density and simplifies FPGA pin-count planning. The FemtoCharge architecture minimizes sample-and-hold charge injection and reduces aperture uncertainty, resulting in excellent SNR at high input frequencies - critical in radar, broadband communications, and digital oscilloscope front-ends. Typical applications include multi-carrier GSM/UMTS/LTE base-station receivers, cable-infrastructure digitization, radar and electronic-warfare signal capture, test and measurement instrumentation, and medical imaging front-ends such as ultrasound beamformers. The 130 MSPS grade is well suited to intermediate IF sampling in software-defined radio (SDR) platforms and to high-channel-count phased-array antenna systems where deterministic latency is mandatory. When integrating the ISLA216S13IR1Z into a PCB, allocate a continuous ground plane beneath the exposed pad, route the JESD204B lanes as 100-ohm differential pairs with length matching to within a few millimeters, and keep the analog input traces short and surrounded by ground. Decouple AVDD and DVDD rails independently at the pins with low-ESL ceramic capacitors. Verify the FPGA's JESD204B IP core supports the chosen lane count and lane rate before final BOM lock.

ISLA216S25IR1Z

ISLA216S25IR1Z - 16-Bit 250MSPS JESD204B ADC | Renesas

The Renesas (formerly Intersil) ISLA216S25IR1Z is a 16-bit, 250 MSPS, high-speed analog-to-digital converter with a JESD204B-compliant high-speed serial output, fabricated in a standard CMOS process using Renesas FemtoCharge™ technology. Housed in a 48-pin LQFN (Hawk) package, it delivers state-of-the-art dynamic performance for demanding wideband signal-chain applications. What is a high-speed JESD204B ADC? A high-speed analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous-time analog signal at high rates (tens to hundreds of MSPS) and outputs a discrete digital word for downstream processing. When the data interface uses the JESD204B standard (JEDEC standard for serial data conversion interfaces), the converter streams its digital output over a small number of high-speed serial lanes, eliminating parallel LVDS routing and reducing PCB complexity. The ISLA216S25 family belongs to the broader category of pipeline ADCs (successive pipeline architecture) within the data-converter market segment. Key headline specifications include 16-bit resolution, 250 MSPS maximum sample rate, JESD204B serial interface, low-latency digital processing, integrated input buffer / output drive, and configurable lane counts. The FemtoCharge™ architecture minimises aperture uncertainty and provides clean spurious-free dynamic range (SFDR) when driven by demanding wideband IFs. Typical applications for this ADC family include digital oscilloscopes, wideband communication test equipment, software-defined radio (SDR) platforms, radar and lidar receivers, medical imaging front-ends (ultrasound beamforming), and spectrum analysers. The serial JESD204B interface makes it well-suited to FPGA-based processing pipelines such as those built on Xilinx Kintex/Vertex and Intel/Altera Stratix families. A critical design consideration when using this part is matched impedance routing of the JESD204B serial lanes; reference clock jitter at sub-picosecond levels is required to realise 16-bit noise floor performance. The internal input bandgap and reference structure are calibrated at the factory, so designers only need to provide clean low-noise analog and clock supplies.

ISLA222P20IRZ

ISLA222P20IRZ - Dual 12-Bit 200MSPS ADC, 72-QFN | Renesas

The Renesas (formerly Intersil) ISLA222P20IRZ is a dual-channel 12-bit analog-to-digital converter from the ISLA222P family, supporting a maximum sampling rate of 200 MSPS and housed in a 72-pin QFN (10x10 mm) package with an exposed thermal pad. The device implements Intersil's proprietary FemtoCharge™ technology on a standard CMOS process, enabling high dynamic performance with low power dissipation suitable for communications, medical imaging, and defense signal-chain applications. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts a continuous-time analog voltage into a discrete digital code, acting as the critical bridge between the analog physical world and a digital processor. ADCs are grouped by architecture (SAR, pipeline, sigma-delta, flash) and resolution/speed trade-off; high-speed pipeline ADCs like the ISLA222P20 target the bandwidth tier where flash is impractical and SAR cannot keep pace, sitting within the broader mixed-signal and data-converter IC hierarchy. Key features of the ISLA222P20IRZ include 12-bit resolution across two simultaneous sampling channels, 200 MSPS maximum conversion rate, parallel CMOS or LVDS digital output interfaces, and an SPI-configurable port for gain, offset, and mode control. The FemtoCharge™ switched-capacitor architecture delivers excellent SNR/SFDR for IF-sampling receivers, while the integrated input buffer and on-chip reference simplify board-level design. The ISLA222P is part of a pin-compatible portfolio spanning 12-bit and 14-bit dual ADCs with sample rates from 130 MSPS to 250 MSPS, allowing designers to scale performance without changing the PCB footprint. Internal calibration logic maintains performance across temperature, and the exposed-pad QFN package provides low thermal resistance for the moderate power dissipation typical of the family's operating point. Typical applications include cellular base-station receive paths, radar and EW digitizers, portable instrumentation, medical ultrasound receivers, and high-speed data acquisition systems. Designers choose the ISLA222P20IRZ when they require dual simultaneous sampling at IF with low spurious content in a compact surface-mount footprint. When designing with this device, ensure the analog inputs are AC-coupled or DC-biased within the common-mode range specified in the datasheet, and provide low-impedance ground returns on the exposed pad for thermal and electrical performance. Use the SPI port to optimize gain and offset for each channel independently.

ISLA222S12IR1Z - Dual 12-bit 125 MSPS JESD204B ADC | Renesas

The Renesas ISLA222S12IR1Z is a dual-channel, 12-bit, 125 MSPS analog-to-digital converter with a JESD204B-compliant high-speed serial output, housed in a 48-pin QFN-EP package. The ISLA222S family is built on Renesas FemtoCharge technology on a standard CMOS process, and shares the same analog core as the proven ISLA222P series. The 'IR1Z' suffix denotes the industrial temperature grade and 48-pin QFN-EP tray packaging. An ADC (analog-to-digital converter) is a data converter integrated circuit that samples continuous analog signals and quantizes them into discrete digital codes for downstream processing by FPGAs, ASICs, DSPs, or microcontrollers. High-speed dual-channel ADCs sit at the front end of digital signal chains in communications, defense, and test equipment, where they convert IF or baseband analog signals into digital streams. Within the data-converter taxonomy, the ISLA222S12IR1Z is a pipelined ADC -> successive-approximation/pipelined hybrid -> data converter -> signal-chain IC -> semiconductor. Key features include 12-bit resolution, 125 MSPS maximum sampling rate per channel, two simultaneously-sampling channels, a JESD204B subclass 0/1/2 serial output interface, integrated input buffer, internal sample-and-hold, and a typical SNR of 69.5 dBFS at 70 MHz input. The QFN-EP package offers an exposed thermal pad with low thermal resistance suitable for continuous-conversion industrial environments. The ISLA222S12IR1Z uses FemtoCharge switched-capacitor pipeline architecture, which reduces the number of comparators per stage relative to conventional flash front-ends, cutting power consumption while preserving linearity. Internal calibration corrects gain and offset drift across temperature, supporting the industrial -40C to +85C operating range. Typical applications include radar and phased-array signal chains, software-defined radio (SDR) receivers, medical imaging front-ends, communications test equipment, and high-speed data acquisition systems. The JESD204B serial interface simplifies board routing by replacing parallel LVDS with one or two serialized lanes, reducing FPGA pin count and PCB trace congestion. When designing with this part, follow the JESD204B link-setup procedure in the datasheet: configure the FPGA receiver to detect K28.5 commas, negotiate lane alignment via the SYNC~ signal, and use the SYSREF input for deterministic multi-device synchronization. Decouple AVDD/AVSS with low-ESL 100 nF + 10 uF ceramics adjacent to each pin pair.

It uses the FemtoCharge™ technology on a standard CMOS process and provides JESD204B subclass 1 high-speed serial data output, which simplifies multi-lane synchronization and reduces board-routing complexity in high-channel-count systems. An ADC (analog-to-digital converter) is an integrated circuit that samples continuous analog signals and converts them into discrete digital codes for processing by FPGAs, ASICs, or microprocessors. Within the system hierarchy, the ISLA222S25IR1Z sits in the signal chain between the analog front end (amplifiers, filters, drivers) and the digital processing block; its sampling rate, resolution, and interface protocol determine the achievable instantaneous bandwidth and dynamic range of the receiving system. The JESD204B subclass 1 standard transport layer ensures deterministic latency across multiple converters, which is essential for beamforming, phased-array radar, and multi-channel test instruments where sub-sample timing alignment matters. Key features include dual 12-bit channels at 250 MSPS (200/125 MSPS variants available in the same family), 7.4 effective number of bits at Nyquist, integrated multi-chip synchronization for multi-lane alignment, automatic and power-on calibration for gain and offset, a soft reset pin, and a 1.8 V analog/digital supply with low power consumption. The 48-QFN (7x7) plastic package is RoHS-compliant and uses a heat-spreading exposed pad for thermal management. The FemtoCharge™ switched-capacitor architecture keeps aperture latency small and consistent across temperature, while the on-chip calibration engine continuously trims gain and offset. Together these features yield excellent spurious-free dynamic range and signal-to-noise ratio across the second and third Nyquist zones, supporting direct IF sampling and high-IF telecom designs. Typical applications include multi-channel software-defined radio receivers, phased-array radar and sonar front-ends, medical imaging systems, high-end oscilloscopes and digitizers, communications test equipment, and broadband satellite receivers where dual-channel alignment and deterministic latency are mandatory. When designing with this ADC, route the JESD204B serial lanes with 100-ohm differential impedance and length-match traces within the inter-pair skew budgets defined in the Renesas JESD204B hardware design guide. Decouple AVDD and DVDD pins individually with 1uF and 0.1uF capacitors, and bond the exposed pad to a continuous ground pour to maintain the package thermal resistance.

ISO100AP - Optically Coupled Isolation Amplifier | Texas Instruments

The Texas Instruments ISO100AP is an optically coupled linear isolation amplifier with one isolation channel, 60 kHz bandwidth, 750 V continuous isolation, and an 18-CDIP through-hole package. The verified distributor description identifies it as a single-circuit isolation amplifier, while the archived manufacturer data describes a device that accepts current or voltage inputs and transfers the measured signal across an optical isolation barrier. Its wide bandwidth supports dynamic instrumentation signals, although the 60 kHz figure should be matched carefully against the required signal bandwidth. An isolation amplifier is an analog signal-conditioning component that transfers a differential input to an output while providing galvanic isolation between input and output grounds. In the signal-chain hierarchy, an isolation amplifier sits between sensors, transducers, and amplifiers and downstream data converters or measurement systems. Optocoupling inside the ISO100AP reduces conductive coupling between the two sides, helping protect sensitive equipment from high common-mode voltage and ground-potential hazards. The available feature data highlights simple feedback-set gain relationships, 100% tested 750 V continuous isolation, ultra-low leakage of 0.3 µA maximum at 240 V/60 Hz, and wide bandwidth. For a current input, the output relationship is VOUT/IIN = RF; for a voltage input, the relationship is VOUT/VIN = RF/RIN. These relationships allow an engineer to select external resistors for the desired conversion gain while retaining the device's isolated signal path. The ISO100AP is suited to industrial current sensing, medical monitoring, laboratory instrumentation, data acquisition, and power-system measurement where the input and output domains must remain electrically separated. The 18-CDIP package is appropriate for through-hole PCB construction rather than compact surface-mount designs. Because the verified data does not provide the complete electrical table or a complete pin map, designers should consult the manufacturer datasheet before finalizing supply voltages, gain accuracy, common-mode range, slew rate, and isolation ratings. A key design consideration is to keep the input-side and output-side return paths separate and to place the external gain-setting resistors close to their associated pins. Verify the required bandwidth and input common-mode range against the 60 kHz device description. The ISO100AP should be selected when optical isolation and the verified 750 V continuous isolation rating justify the through-hole package and external resistor configuration. This page combines verified distributor product descriptions, an archived manufacturer datasheet listing, package information, practical signal-chain guidance, and transparent sourcing limits.

These headline capabilities place it in the isolation-amplifier and instrumentation-amplifier hierarchy, where a sensor signal crosses a high-voltage barrier without a direct galvanic connection. An isolation amplifier is a precision analog signal-conditioning device used when a measurement originates on an electrically hazardous, high-impedance, or ground-referenced circuit. It combines input-stage gain, electrical isolation, and output amplification so that a low-level sensor signal can be transferred to a measurement system while minimizing ground-loop errors and common-mode hazards. The ISO100BP’s optically coupled architecture supports industrial instrumentation, process control, medical monitoring, and other applications requiring reinforced signal separation. Verified product information identifies one isolation-amplifier circuit, an 18-CDIP package, through-hole mounting, 18 terminals, 8 mA supply current, a 60 kHz operating description, and 18-pin construction. The datasheet search result also states that the device is 100% tested for 750 V continuous isolation, has maximum ultra-low leakage of 0.3 µA at 240 V and 60 Hz, and accepts current or voltage input configurations. Exact gain, supply-voltage, accuracy, and temperature limits were not supplied in the verified data and therefore require confirmation from the manufacturer datasheet before design release. The device is intended for analog front ends where preserving signal integrity across an isolation barrier is more important than minimizing package size. Its through-hole CDIP construction can simplify prototyping and repair, while the isolation barrier allows a field-side input circuit and a grounded output interface to remain electrically separate. Input and output grounding, supply bypassing, component tolerances, and barrier creepage must be evaluated as a complete isolation system rather than inferred from the amplifier alone. Typical uses include isolated current measurement, industrial process sensors, laboratory instrumentation, and medical or diagnostic signal acquisition. In each case, the sensing front end can operate near a high-voltage node while the output is referenced to a lower-voltage system. The design must still account for input common-mode range, isolation capacitance, leakage, bandwidth, gain configuration, supply sequencing, and applicable safety requirements. For a new design, use the ISO100BP when its verified 18-CDIP footprint, current-or-voltage input flexibility, 60 kHz bandwidth description, and 750 V continuous isolation rating fit the mechanical and safety requirements. Do not substitute an unspecified amplifier solely by function; verify every pin, parameter, creepage dimension, and isolation requirement against the official datasheet.

ISO100CP - 750V Isolation Amplifier, 60kHz | Texas Instruments

The Texas Instruments ISO100CP is an optically coupled isolation amplifier rated for 750 V continuous isolation voltage, featuring a 60 kHz signal bandwidth and a maximum input-side leakage current of 0.3 uA at 240 V RMS, 60 Hz. It is packaged as a single-channel amplifier in an 18-pin CDIP measuring 0.300 inch, or 7.62 mm. An isolation amplifier belongs to the signal-chain hierarchy of operational amplifiers and instrumentation amplifiers, but its defining function is galvanic isolation between input and output domains. This category transfers an analog measurement across a high-impedance barrier while limiting electrical current between the two sides. The ISO100CP is therefore suited to systems where a sensor or shunt is electrically connected to hazardous, high-voltage, or earth-referenced equipment that must remain separately controlled. The part supports two transfer relationships identified in the source material: VOUT/IIN equals RF for current-input use and VOUT/VIN equals RF/RIN for voltage-input use. Its 100% tested 750 V continuous isolation capability supports robust reinforced separation where the application and system safety requirements permit. The 60 kHz bandwidth is suitable for measurement signals that need accurate transfer without operating as an ultra-low-frequency instrumentation amplifier. Optically coupled internal construction provides the barrier function, while the external resistors establish current- or voltage-to-output scaling. Because the verified source does not publish the complete electrical tables or a complete pin map, resistor values, gain tolerance, supply limits, common-mode range, and settling performance should be taken directly from the manufacturer datasheet before design release. Verify that the complete 18-pin CDIP footprint and pin names match the target PCB. Typical uses include isolated current measurement, power-converter control feedback, industrial sensor interfaces, instrumentation channels, and high-voltage test equipment. The key engineering consideration is that isolation rating does not replace application-specific safety design: creepage, clearance, barrier construction, insulation coordination, and enclosure requirements must be evaluated separately. The ISO100CP combines a 60 kHz isolation-amplifier channel, 750 V continuous isolation rating, 0.3 uA maximum leakage specification, and 18-CDIP package in one through-hole device. It is appropriate when the system needs a conventional resistor-programmed isolation signal path rather than a small surface-mount digital isolator. This page synthesizes the supplied distributor information, manufacturer-linked datasheet material, package facts, sourcing context, and design cautions. Because no verified pin-compatible substitute was returned by the cross-reference search, it does not invent a five-part replacement list or present unreferenced competitor devices as drop-in alternatives.

ISO102 - 1500Vrms Isolation Buffer Amplifier | Texas Instruments
ISO102

ISO102 - 1500Vrms Isolation Buffer Amplifier | Texas Instruments

The Texas Instruments ISO102 is a low-cost, high-voltage, wide-bandwidth standard hermetic DIP signal isolation buffer amplifier offering 14-bit linearity and capacitive-coupled isolation rated at 1500Vrms in a 24-pin side-brazed ceramic DIP (600 mil wide). It belongs to TI's Burr-Brown isolation amplifier family and is the industry's first hermetic isolation amplifier offered at a low cost with industry-standard pinout. An isolation amplifier is a specialized analog device that combines a precision operational amplifier with an isolation barrier to transmit a signal across a galvanic isolation boundary while rejecting common-mode voltages. These devices are essential in industrial, medical, and process-control systems where the input side must be physically and electrically separated from the output side to protect users, downstream circuitry, or measurement equipment from high voltages, ground loops, and transient events. The ISO102 specifically uses capacitive-coupled isolation technology with high-voltage ceramic capacitors embedded inside the package, achieving 125 dB IMR (isolation mode rejection) and 100% tested 3500Vrms/1 min high-voltage breakdown rating. Key features include a wide bandwidth of 60 kHz, low nonlinearity of 0.05% (14-bit accuracy), ±10V output swing, and an easy-to-use complete circuit that requires no external components. The rugged HV ceramic barrier delivers consistent performance over temperature, and the hermetic 24-pin side-brazed DIP package supports harsh-environment and military temperature grade operation. The ISO102 employs a duty-cycle modulation/demodulation scheme across an internal differential capacitive barrier, allowing analog signals to pass with excellent common-mode transient immunity (CMR) while rejecting DC common-mode voltages up to 1500Vrms continuous. The same electrical performance is offered by its companion part ISO106, which is rated for 3500Vrms in a larger 40-pin DIP package. Compared to optocoupler-based isolation, the capacitive topology of ISO102 delivers superior linearity and bandwidth stability over time and temperature. Typical applications include process-control signal isolation, biomedical instrumentation, ground-loop elimination in data acquisition systems, motor drive current sensing, and 4-20 mA loop isolation. The hermetic package also makes it suitable for aerospace, military, and downhole oilfield equipment. When designing with this part, note that the 24-pin DIP package is not pin-compatible with the higher-voltage ISO106 (40-pin) or with modern surface-mount isolation amplifiers such as the TI ISO224. The 1500Vrms rating requires a minimum 5 mm clearance and creepage distance on the PCB, and any flux residue must be cleaned after soldering to preserve the high-voltage isolation barrier.

ISO102B - High-Voltage Isolation Buffer Amplifier | Texas Instruments

The Texas Instruments ISO102B is a low-cost, high-voltage, wide-bandwidth, hermetic-DIP signal isolation buffer amplifier with 1 channel in a 16-pin CDIP (J Package) ceramic package. The device operates from ±10V to ±20V dual supplies and provides up to 70 kHz small-signal bandwidth while delivering a capacitive barrier isolation of 1500 Vrms (continuous), 2500 Vrms (1 s test), and 6000 V peak transient overvoltage protection per UL 544/VDE Class V safety targets. What is an isolation buffer amplifier? An isolation amplifier is an analog front-end device that transfers a small differential signal across a galvanic isolation barrier while rejecting high common-mode voltages between input and output grounds. Inside the ISO102 family, a low-level input stage modulates a carrier that crosses a capacitive barrier; the receiver demodulates and reconstructs the signal. Compared to opto-isolated or transformer-based isolators, the capacitive-barrier design of the ISO102/ISO120 family preserves analog linearity and bandwidth, making the device a fundamental building block in medical, industrial, and process-control signal chains where patient safety or ground-loop protection is mandatory. Key features include 1.4 mV maximum input offset voltage (B grade), low input bias current, a unity-gain buffer input stage, and integrated short-circuit-protected output. The unit delivers 2500 Vrms continuous (1 s test) isolation rating. The hermetic side-brazed ceramic DIP (16-CDIP) package provides a wide operating temperature range and meets the reliability expectations of military, aerospace, and down-hole instrumentation programs. The ISO102B uses a duty-cycle modulation-demodulation topology with a 2pF differential capacitive isolation barrier. Unlike transformer or optocoupler isolators, this capacitive approach delivers excellent common-mode transient immunity (CMTI) and preserves DC accuracy down to sub-Hz frequencies. Internal ±15V regulators on each side of the barrier decouple the barrier from supply noise, allowing clean operation from poorly filtered industrial rails. Typical applications include ECG/EEG patient monitoring front-ends, industrial 4-20 mA loop isolation, motor-drive IGBT gate-driver analog feedback, high-voltage test equipment signal paths, and process-control analog I/O modules. The wide 70 kHz bandwidth supports thermocouple, strain-gauge, and flow-meter signal conditioning where the input signal is several volts above earth ground. When designing with the ISO102B, place decoupling capacitors as close as possible to both the input-side and output-side supply pins (1 µF ceramic minimum), and use a 0.1 µF bypass cap for high-frequency noise. Maintain at least 8 mm of creepage/clearance on the PCB to preserve the 2500 Vrms isolation rating and avoid routing any conductor under the package that would compromise the barrier. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers select a true pin-to-pin equivalent and accelerate design-in.

ISO103 - 20kHz Internally Powered Isolation Amp | TI
ISO103

ISO103 - 20kHz Internally Powered Isolation Amp | TI

The Texas Instruments ISO103 is a low-cost, internally powered isolation amplifier with a 20 kHz bandwidth, one amplifier circuit, and a 16-lead CDIP package. Its verified isolation test voltage is 5600 Vpk, while the continuous AC barrier rating is 1500 Vrms. The input signal range extends to +10 V, and the device is described as operating at 20 kHz both for small-signal and full-power bandwidth. An isolation amplifier is a differential amplifier whose input and output domains are electrically separated by a reinforced isolation barrier. In the broader hierarchy, ISO103 belongs to the isolation-amplifier class, then to instrumentation amplifiers, then to analog signal-conditioning ICs and semiconductors. This category transfers low-frequency or low-frequency-plus-audio-band analog information across a high-voltage barrier without requiring a direct electrical connection between the two sides. The principal verified features include internal power, a wide input signal range of +10 V, 20 kHz small-signal bandwidth, and 20 kHz full-power bandwidth. The manufacturer’s datasheet description also identifies the device as a low-cost isolation amplifier. These values position ISO103 for analog isolation, instrumentation, industrial control, and signal-conditioning systems where bandwidth, barrier rating, and a through-hole package are more important than miniature packaging. The 16-CDIP construction is mechanically significant for systems that use conventional through-hole PCB assembly rather than fine-pitch surface-mount parts. A distributor listing identifies ISO103 as a 16-CDIP isolation amplifier, while another listing identifies a 24-CDIP package for a related representation; the target data therefore preserves the target package as 16 leads and flags package-specific verification where the supplied snippets conflict. ISO103 is an analog IC, so a safe-operating-area chart is not applicable. Typical applications include isolated sensor interfaces, industrial process-control signal paths, power-inverter feedback, medical monitoring signal isolation, test and measurement input conditioning, and communication-interface isolation. The 20 kHz bandwidth is suitable for many analog control and measurement signals, but it should not be interpreted as a high-speed digital isolation or RF isolation solution. The 5600 Vpk test voltage and 1500 Vrms continuous AC barrier rating are the verified isolation-related figures available from the supplied data. Designers should confirm the exact pinout, input polarity, supply requirements, gain configuration, isolation limits, and system-level creepage and clearance before layout. The supplied web results identify the device and its major isolation and bandwidth characteristics, but do not provide a complete authoritative electrical table, recommended PCB land pattern, or detailed application circuit.

ISO103B - Internally Powered Isolation Amplifier | Texas Instruments

The Texas Instruments ISO103B is an internally powered isolation amplifier with a 20 kHz bandwidth, 1500 Vrms continuous AC barrier rating, and a 16-CDIP ceramic package. It combines input signal conditioning and galvanic isolation in one device, making it suitable for industrial measurement and control systems. The isolation barrier is specified as 5600 Vpk test voltage, while the wide input signal range supports signals beyond conventional low-level sensor outputs. An isolation amplifier is a type of instrumentation amplifier that transfers a signal across a galvanic barrier while preventing conductive current from flowing between the input and output domains. This protects sensitive measurement equipment from high common-mode voltages, ground faults, and potentially hazardous electrical environments. The ISO103B belongs to the broader signal-chain and isolation-IC hierarchy rather than a conventional non-isolated operational amplifier. Key features include integrated signal and power handling in one double-wide, 0.6-inch side-brazed package; 5600 Vpk test voltage; 1500 Vrms continuous AC barrier rating; and a specified 20 kHz small-signal and full-power bandwidth. The internally powered architecture simplifies system design by reducing the number of external isolation-supply components. The 16-terminal CDIP package is intended for through-hole industrial and laboratory equipment. Technically, the device combines an isolated input stage, isolation barrier, and output amplifier. Its bandwidth limits the fastest transient and signal behavior, while its continuous barrier rating addresses sustained AC isolation rather than only a short-duration production test. Designers must consider the complete isolation path, creepage, clearance, barrier insulation, and the datasheet pinout before applying the part to a high-voltage installation. Typical uses include current and voltage measurement, process-control instrumentation, data acquisition, power-supply feedback isolation, laboratory signal conditioning, and industrial sensor interfaces. The 20 kHz bandwidth is appropriate for many measurement signals but not for high-frequency communications or waveform systems requiring greater bandwidth. A critical design consideration is to preserve the intended isolation barrier and avoid unintended copper bridges or leakage paths. PCB layout, creepage, clearance, input filtering, grounding, and the package’s mechanical orientation must be reviewed against the manufacturer datasheet.

ISO1042BQDWRQ1 - 5 Mbps Isolated CAN FD Transceiver | Texas Instruments
ISO1042BQDWRQ1

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.

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.

A CAN transceiver is the physical-layer interface between a CAN controller and a Controller Area Network bus. It converts logic-level transmit and receive signals into differential CAN bus signals, while providing galvanic isolation between those domains. This separation reduces ground-potential and fault-energy paths, making the transceiver suitable for electrically demanding automotive, industrial, and communications equipment that uses the ISO11898-2 CAN standard. Key features include a maximum data rate of 5 Mbps in CAN FD mode, ±70-V DC bus-fault protection, and a ±30-V common-mode range. The 16-pin SOIC package provides enough pins for the isolated logic interface, isolation barrier, CAN bus side, and bypass connections. The automotive-rated ISO1042-Q1 family is intended for systems where robust fault handling and high-speed CAN FD communication are important. The ISO1042-Q1 architecture separates the controller-side TXD and RXD signals from the CANH and CANL bus terminals with an internal isolation barrier. Its high fault tolerance lets the bus interface withstand severe DC bus faults without immediately compromising the logic side. During normal operation, the bus side supports high-speed CAN FD communication, while the isolated logic side connects to a CAN controller through digital transmit, receive, enable, and power connections. Typical uses include automotive body and chassis controllers, electric-vehicle power domains, industrial automation equipment, robotics, medical carts, and other embedded systems that need a robust isolated CAN interface. In an automobile, the transceiver can connect a low-voltage controller to a CAN bus exposed to battery transients and wiring faults. In factory equipment, isolation helps bridge control electronics and field-bus wiring across different ground references. Design the PCB with short CANH and CANL traces, a continuous return path beneath the bus pair, and the bus-side bypass capacitor placed close to the device. Keep isolation-side and bus-side copper areas separated according to the Texas Instruments datasheet layout guidance. The isolation barrier components and supply networks must also follow the specified creepage and clearance requirements, particularly in high-voltage automotive environments.

ISO1042QDWVQ1 - 5Mbps Isolated CAN FD | Texas Instruments

The Texas Instruments ISO1042QDWVQ1 is an automotive galvanically isolated CAN FD transceiver supporting data rates up to 5 Mbps, ±70-V DC bus fault protection, and a ±30-V common-mode voltage range. It is designed around the ISO11898-2:2016 CAN standard and is available in the ISO1042-Q1 family for isolated controller area network communication. A CAN transceiver is the physical-layer interface between a CAN controller and a two-wire differential bus. ISO1042-family devices combine bus-driver and receiver functions with digital isolation, allowing a controller-side logic domain to communicate with a bus-side domain while reducing common-mode and ground-potential hazards. This transceiver belongs to the CAN interface IC, interface IC, and semiconductor hierarchy used in automotive and industrial networks. Key features include operation up to 5 Mbps in CAN FD mode, ±70-V DC bus fault protection, and a ±30-V common-mode range. The isolation barrier separates logic-side and bus-side circuits, while flexible data rate support permits substantially faster payload transfer than classical CAN. These characteristics suit systems that must combine high-speed data transfer with robust protection against automotive electrical transients. The ISO1042-Q1 family meets the ISO11898-2:2016 specification and is positioned for automotive and industrial CAN networks. Its primary interface functions include transmit, receive, bus-fault handling, and isolation. The 16-pin wide-body SOIC package supports surface-mount assembly while providing enough lead spacing for inspection and rework in demanding electronics manufacturing processes. Typical applications include electric-vehicle powertrain and body networks, industrial automation equipment, robotics controllers, diagnostic systems, and isolated CAN links between high-voltage systems and low-voltage controllers. In these systems, the isolated transceiver can link a CAN FD-capable controller to a protected network while helping maintain functional separation between circuit domains. Designers should pay close attention to bus termination, common-mode range, grounding, isolation-capacitor placement, and the exact pin assignments in the manufacturer datasheet. The 5-Mbps operating rate also requires controlled printed-circuit-board layout, short differential routing, and compliant CAN physical-layer timing. Automotive programs should additionally verify qualification, traceability, and sourcing requirements with the manufacturer. This page combines the manufacturer specifications, practical isolation-interface guidance, a same-package replacement comparison, and selection criteria that help engineers distinguish electrical protection, automotive qualification, and interface compatibility before committing a board design.
