STB-835 - AN & DIG Panel for I/O | Analog Devices
The Analog Devices STB-835 is an analog and digital panel for I/O, classified by LCSC as an Interface - Specialized integrated circuit. The verified listing identifies the MPN as STB-835 and the manufacturer as Analog Devices, while the available distributor records provide sourcing information rather than a complete electrical datasheet. The supplied listing does not establish the package, pin count, supply-voltage range, signal count, operating temperature, or environmental ratings; those parameters must be confirmed from the manufacturer documentation before design release. An interface IC is a semiconductor that connects a controller, panel, test fixture, or external circuit through analog and digital signal paths. A panel-for-I/O device commonly organizes input and output functions into a defined interface structure, allowing a system to monitor or control external lines through a standardized connection arrangement. Unlike a general-purpose logic IC, a specialized interface panel may combine input conditioning, output drivers, isolation, or panel-specific routing, but the exact functions of STB-835 are not available in the supplied verified records. The strongest verified product facts are the manufacturer identity, the functional description “AN & DIG PANEL FOR I/O,” the Interface - Specialized classification, and the listed commercial availability. LCSC reports the part as in stock and states a price from $61.5230 as of the supplied 2026-10-23 search timestamp. DigiKey, JLCPCB, Octopart, Cytech Systems, and other listings provide purchasing or comparison entry points, but their snippets do not expose enough technical detail to populate electrical specifications without fabrication. STB-835 should therefore be treated as a procurement-qualified interface component with incomplete application-level characterization. Before placing it in a PCB design, obtain the official Analog Devices datasheet or approved Rochester Electronics documentation and verify the exact package drawing, pin names, signal directions, voltage domains, timing, power consumption, and environmental limits. The listed Rochester Electronics association may indicate legacy or specialty sourcing, but it does not establish lifecycle status, obsolete designation, or a direct replacement. Typical design work involves mapping every panel connection to the verified pinout, checking voltage-domain compatibility across connected analog and digital signals, and validating input thresholds and output drive capability before layout. Because no verified package or pinout is supplied, PCB footprint selection must not be inferred from distributor category data. This page distinguishes verified commercial information from missing technical data so procurement and engineering teams can identify the next required verification step. This page combines verified distributor availability, pricing, sourcing links, and explicit data gaps with engineering guidance for evaluating a specialized interface panel. It intentionally avoids guessing pin assignments, electrical limits, lifecycle claims, compliance status, or substitute parts that could create an unsafe PCB redesign.
STB-BB05 - RTI204/205 Interface Panel IC | Analog Devices
The Analog Devices STB-BB05 is an RTI204/205 interface-panel integrated circuit offered in bulk packaging. The verified listing identifies it as an Analog Devices component associated with the Telecom & Specialized integrated-circuit family, while one distributor record categorizes it as a Specialized interface IC. Its exact electrical ratings, pin arrangement, and mechanical dimensions are not exposed in the supplied sources. The available catalog information instead confirms the device identity, manufacturer association, interface-panel role, bulk order form, and sourcing status. Engineers should therefore treat this page as a procurement and identification resource rather than a substitute for the original manufacturer documentation. An interface-panel IC is a type of integrated circuit that connects external equipment, control signals, or peripheral circuitry to a system interface. In the telecommunications and specialized-equipment hierarchy, such a device sits between discrete connectors and higher-level communication electronics: connectors provide the physical path, the interface IC conditions or translates signals, and the host system performs control and data processing. The supplied distributor description associates STB-BB05 specifically with RTI204/205 interface-panel applications, making those panel functions the central application context. The available evidence confirms the MPN STB-BB05, Analog Devices branding, specialized-interface classification, and bulk packaging. One supplier lists a minimum order quantity of 2, while other listings direct buyers to submit an RFQ to confirm stock, date code, and lead time. A Rochester Electronics record reports the component as active. These facts make STB-BB05 potentially relevant to repair, maintenance, replication, and legacy-system support, but production use still requires confirmation of environmental ratings, supply conditions, and pin compatibility. Technically, the available data does not identify whether the device is a surface-mount or through-hole part. Rochester Electronics lists mounting type and package as unavailable, while another supplier describes the shipment format as Bulk. Because the exact package is unknown, no package-specific land pattern, pinout diagram, thermal calculation, or drop-in replacement claim can be supported. This uncertainty is especially important for proprietary interface hardware, where similar connector functions do not guarantee signal-level or timing compatibility. Typical sourcing uses for STB-BB05 include RTI204/205 interface-panel maintenance, specialized telecommunications equipment repair, legacy system restoration, and component matching during low-volume production. For each use, the engineer should verify the original equipment schematic, pin connections, supply requirements, logic levels, and timing before installation. The listing supports component identification and RFQ-based procurement, but does not provide enough technical data to establish those electrical requirements independently. The principal design consideration is to avoid assuming compatibility from the RTI204/205 description alone. Before procurement, request the manufacturer datasheet, drawing, revision status, and inspection information from the supplier or original equipment manufacturer. Also confirm whether the offered unit is an original packaged component, a screened assembly, or an alternate-source item. These checks are essential because a catalog listing can confirm identity and sourcing availability without confirming electrical equivalence or manufacturing provenance. This page consolidates the supplied distributor identities, lifecycle statement, interface classification, package uncertainty, and procurement references. It intentionally avoids fabricating electrical values, pin names, package dimensions, pricing, or cross-references that were absent from the verified sources.
STB-GP - RT1850/RT1860 Panel | Analog Devices | Telecom
The Analog Devices STB-GP is a specialized interface panel identified for use with RT1850 and RT1860 assemblies, available from distributors as an active or in-stock component. The verified product listing identifies STB-GP as “PANEL FOR RT1850 RT1860,” while Rochester Electronics describes the device as belonging to the Telecom & Specialized integrated-circuit family. Its public listing does not provide a conventional IC package, pinout, electrical ratings, interface protocol, or mounting data, so those details remain unverified rather than inferred. The STB-GP designation therefore should be treated as a specialized panel or module-related procurement item until the manufacturer documentation is obtained. A specialized interface IC or panel is used to connect, route, adapt, or terminate signals within a larger telecom, networking, or embedded system. The STB-GP listing connects this item with RT1850 and RT1860, which are identified by the source data as related assemblies, but the exact electrical role, signal directions, connector arrangement, and supported system configuration are not provided. Engineers should therefore confirm the system revision and board connector before ordering or substituting it. The available commercial evidence indicates availability rather than a complete technical datasheet. LCSC lists STB-GP as in stock with a starting price of $69.6681, eBee lists a starting price of $73.2624, and Rochester/FPGACenter lists a starting unit price of $146.99 with volume discounts for quantities of 10, 100, 500, and 1,000. Prices are reproduced as reported and may change without notice as of 2026-10-23. Octopart also lists Analog Devices STB-GP and directs buyers to compare bulk pricing and availability. Because the verified sources do not specify package dimensions, pin count, mounting type, operating temperature, voltage, current, RoHS, REACH, or automotive qualification, this page does not invent those values. The procurement-critical decision is compatibility with the intended RT1850/RT1860 assembly, not an assumed generic IC replacement. Request the current Analog Devices or Rochester Electronics documentation, mechanical drawing, and revision information before using the part in a new design. This page combines verified distributor identity, reported pricing, lifecycle information, sourcing links, and explicit data gaps. It is intended to help engineers identify STB-GP quickly while preventing unsupported assumptions about electrical compatibility, package fit, or drop-in replacement.
STB-TCI - Isolated Analog Signal Conditioning Panel | Analog Devices
The Analog Devices STB-TCI is an isolated analog signal-conditioning panel intended for applications requiring high electrical isolation, with the manufacturer classifying it in the sensor and detector interface domain. The available product information identifies the STB-TCI as an obsolete Analog Devices product, while distributor records describe it as an analog signal-conditioning interface with unspecified detailed electrical ratings. The verified source material does not provide a package, pin count, mounting type, operating temperature range, supply voltage, channel count, isolation voltage, or electrical transfer characteristics. Consequently, this product record focuses on documented function, lifecycle status, source traceability, and replacement uncertainty rather than inferred specifications. According to the Analog Devices product page, the STB-TCI is obsolete. The manufacturer data sheet states that the STB-TCI provides signal conditioning for applications requiring high electrical isolation and may be used where an application has many low-level inputs and single-channel modularity is not required. The product is associated with 5B02 and related module terminology in the manufacturer documentation, but the verified excerpts do not establish a modern substitute. Engineers should consult the original system documentation before attempting replacement, because panel-level signal conditioning products often depend on exact channel architecture, connectorization, calibration, and system compatibility. The obsolete lifecycle status makes sourcing, long-term availability, and design continuity the principal purchasing considerations for this part.
STDP2650AD - HDMI 1.4 DisplayPort Converter | Kinetic Technologies
The Kinetic Technologies STDP2650AD is an advanced DisplayPort-to-HDMI video converter IC with I2C and SPI control interfaces, supplied in an 81-BGA package measuring 8 mm by 8 mm. The converter is associated with HDMI 1.4 support and is intended for systems that need to translate DisplayPort video signals into HDMI-compatible outputs. Its I2C and SPI interfaces provide flexible configuration and control from a host processor, while the integrated converter function reduces the need for external display-format translation hardware. The verified product information identifies the STDP2650AD as a video converter IC in an 81-BGA (8x8) package. A DisplayPort-to-HDMI converter is a semiconductor in the video processing and display interface category. DisplayPort is a digital display interface commonly used to connect computers, graphics systems, and other video sources to monitors. HDMI is a separate digital audio and video interface widely used in consumer electronics, televisions, projectors, and displays. A converter such as the STDP2650AD bridges these interface ecosystems by accepting a DisplayPort input and producing an HDMI output, allowing source equipment and display equipment to operate with different connector standards. The principal verified features of the STDP2650AD are its DisplayPort-to-HDMI conversion function, HDMI 1.4 support, I2C control capability, SPI control capability, and 81-BGA package. The I2C and SPI interfaces allow firmware or system-control logic to configure the converter and manage display-related functions. The 8 mm by 8 mm BGA package supports compact integration on multilayer printed circuit boards, although high-density ball-grid-array assembly requires careful PCB layout, thermal management, and inspection processes. The STDP2650AD is suited to computer monitors, graphics-adapter output cards, docking stations, industrial display systems, digital signage, and audiovisual equipment where a DisplayPort source must connect to an HDMI sink. A design using this converter must account for DisplayPort link requirements, HDMI output characteristics, reference-clock and power-supply implementation, connector integration, and the signal-integrity demands of high-speed video links. The package also requires assembly methods capable of handling fine-pitch BGA connections and adequate thermal pathways. A principal design consideration is that the verified snippets do not provide the complete electrical limits, supported display resolutions, refresh rates, color formats, operating-temperature range, pinout, or reference-design details. Engineers should therefore use the manufacturer datasheet for those values and for the required external components. The converter should be selected only after confirming compatibility among the DisplayPort source, supported HDMI mode, sink capability, control firmware, and system power architecture. This page consolidates verified distributor listings, package information, interface capabilities, and practical integration guidance. It also documents where primary datasheet verification remains necessary, rather than presenting unverified electrical values as guaranteed specifications.
STDP2650ADT - HDMI 1.4 DisplayPort Converter | Kinetic Technologies
The Kinetic Technologies STDP2650ADT is an advanced DisplayPort-to-HDMI video converter IC designed for HDMI 1.4 display conversion and modern digital display interfaces. The device operates from a 1.2 V to 3.3 V supply, supports I2C and SPI control interfaces, and is supplied in an 81-BGA 8 x 8 mm surface-mount package. It is intended for systems that need to translate DisplayPort source signals into HDMI-compatible output signals while preserving programmable control and video-conversion functionality. A DisplayPort-to-HDMI converter is a video interface IC that bridges two display standards. DisplayPort is primarily used by computers, docking stations, monitors, and embedded systems, while HDMI remains common in televisions, projectors, displays, and consumer AV equipment. The converter IC sits between a DisplayPort source and an HDMI sink, handling digital video conversion and associated control signaling. This makes the STDP2650ADT relevant to adapters, docking systems, industrial panels, commercial displays, and embedded video equipment. The verified product information identifies the STDP2650ADT as an HDMI 1.4 video converter with I2C and SPI configuration control. Its 1.2 V to 3.3 V operating supply supports integration with low-voltage digital systems, while the 81-BGA package provides a compact surface-mount solution for multilayer PCB designs. The package format is intended for high-density equipment where connector placement, EMI control, and signal routing determine whether a converter can be implemented reliably. Compared with passive DisplayPort-to-HDMI adapters, an active converter IC can support source negotiation, programmable operating parameters, and system-level control through I2C or SPI. The control interface allows firmware or system logic to identify supported display configurations and manage the converter within a larger video subsystem. Because the verified data does not provide resolution, refresh-rate, color-depth, propagation-delay, operating-temperature, or absolute-maximum details, those specifications should be confirmed in the manufacturer datasheet before release to production. Typical uses include USB-C and Thunderbolt docking stations, DisplayPort-to-HDMI adapters, industrial HMI panels, digital signage, projector interfaces, and embedded display products. In these applications, the converter reduces the need for a separate external adapter and enables a compact board-level implementation. The design must still account for connector compliance, display timing support, power sequencing, ground continuity, and the impedance-sensitive high-speed signal paths. The primary design consideration is that the converter does not remove the need for careful PCB implementation. DisplayPort and HDMI links are high-speed differential interfaces, so trace routing, connector launches, reference planes, and return paths directly affect signal integrity. The STDP2650ADT should be evaluated against the exact source and sink requirements, including HDMI version, supported display timing, HDCP requirements, audio behavior, and the target power architecture. This page consolidates the verified distributor descriptions, package and interface information, sourcing links, and engineering guidance for the STDP2650ADT. It distinguishes confirmed data from specifications that still require datasheet confirmation, helping designers make a faster initial component-selection decision without treating unverified parameters as guaranteed capabilities.
STDP4020AD - DisplayPort Receiver | Kinetic Technologies
Kinetic Technologies STDP4020AD is a DisplayPort receiver IC with a 1.2 V to 3.3 V operating voltage range, I2C control, RGB and YCC video support, and a 164-LFBGA package measuring 12 mm by 12 mm. It converts DisplayPort input signals into configurable LVDS or LVTTL outputs for display and video-processing systems. The receiver supports 8-bit, 10-bit, and 12-bit color, with 12-bit operation limited to YCC 4:2:2 format. A DisplayPort receiver is an interface IC that terminates a DisplayPort source, recovers digital video data, and converts that data for display drivers, panels, scalers, or downstream processing logic. Within the interface hierarchy, the STDP4020AD belongs to the video interface IC class and ultimately the broader integrated-circuit and semiconductor categories. Its flexible output mapping allows one receiver design to interface with different display-controller and panel architectures. The STDP4020AD provides four LVDS output lanes and two 60-bit LVTTL output ports. According to the Kinetic Technologies datasheet, the quad-LVDS interface accepts video signals up to a 400 MHz pixel rate. Configurable lane and channel swapping simplifies PCB routing and helps match internal signal organization to the target display interface. RGB and YCC formats support integration with conventional digital-video pipelines. The device uses an I2C control interface for configuration and integration with a system controller. Its 1.2 V to 3.3 V operating range allows use within systems having separate low-voltage core and higher-voltage interface rails. Output color depth can be selected at 8 bits, 10 bits, or 12 bits, but the 12-bit mode supports YCC 4:2:2 only, making that distinction important when designing for full RGB operation. Typical uses include DisplayPort-to-LVDS conversion in commercial displays, industrial panel interfaces, docking systems, video walls, and embedded display controllers. The 164-LFBGA package supports compact designs but requires careful high-speed layout and a land pattern with fine-pitch escape routing. Thermal performance, power sequencing, connector geometry, and LVDS trace impedance should be evaluated together rather than treated as independent issues. A critical design step is validating DisplayPort input impedance and each LVDS or LVTTL output against the actual connector, panel, and timing requirements. Use the manufacturer's reference layout as the starting point, preserve continuous reference planes, control differential-pair geometry, and provide the documented input, output, and bypass capacitance. System designers should also confirm that the selected output format, color depth, lane mapping, and clocking arrangement match the downstream controller. This page consolidates the verified distributor and datasheet findings for the STDP4020AD, including package, interface, format, pixel-rate, and voltage information. It also distinguishes confirmed drop-in naming variants from unverified substitutes so engineers can make a compatibility decision without treating generic cross-reference results as proof of pin-level equivalence.
STDP4028AB - DisplayPort Transmitter IC | Kinetic Technologies
Kinetic Technologies STDP4028AB is a DisplayPort transmitter IC for secure, high-bandwidth transmission of uncompressed digital audio-video signals, with I2C and SPI control in a 164-LFBGA package measuring 12 x 12 mm. The transmitter is compliant with DisplayPort 1.1a and embedded DisplayPort requirements and implements a single DisplayPort output link comprising four main lanes. A DisplayPort transmitter is an interface IC that converts a parallel or serialized video source into a DisplayPort-compatible output stream. Within the wider hierarchy of video interface ICs, it sits between a graphics or embedded display controller and a DisplayPort or embedded DisplayPort endpoint. Its function allows digital audio and video to pass through docking stations, digital televisions, LCD monitors, set-top boxes, and other consumer audiovisual systems. The verified feature set includes secure transmission, support for uncompressed digital audio-video content, DisplayPort 1.1a compliance, and embedded DisplayPort compliance. Configuration is handled through I2C and SPI interfaces, allowing system firmware to program display timing and operating parameters. The 164-LFBGA surface-mount package supports compact integration but requires careful PCB layout and inspection because its ball pitch and ball count make rework more difficult than with a leaded package. STDP4028AB is intended for high-bandwidth display links where the source system already generates suitable digital video data. The transmitter does not eliminate the need for compliant source-device timing, cable selection, connector implementation, or display-side link training. Its single-link output architecture should be matched against the target display's supported resolution, refresh rate, color depth, and embedded DisplayPort capabilities before schematic release. Typical applications include digital television equipment, LCD monitors, docking stations, set-top boxes, and other consumer audiovisual systems. In a docking-station implementation, the part can bridge host-side video data to a DisplayPort output while firmware manages the link through I2C. In an embedded system, it can support an embedded DisplayPort panel connection where board space is limited and high-density assembly is already required. Designers should use the manufacturer datasheet as the authority for the complete 164-ball pin assignment, lane routing, power requirements, input and output interfaces, and reference circuitry. Signal-integrity routing, solid reference planes, controlled clock distribution, and compliance testing are especially important because a compact BGA package can couple adjacent high-speed nets if layout guidance is not followed. This page consolidates verified distributor catalog information, datasheet excerpts, packaging details, sourcing data, and practical design guidance. It also distinguishes verified facts from missing parameters, helping engineers identify what must be confirmed in the manufacturer datasheet before schematic, layout, or qualification decisions are finalized.
STDP4320BA - DisplayPort 1.2a Splitter | Kinetic Technologies
The Kinetic Technologies STDP4320BA is a high-speed DisplayPort 1.2a splitter integrated circuit with one dual-mode input port and two dual-mode output ports. The device routes DisplayPort, HDMI, or DVI video to two configurable outputs for docking stations, notebooks, video hubs, 4K2K televisions, monitor daisy chains, and digital signage systems. It is supplied in a 172-LFBGA package measuring 12 mm by 12 mm. A DisplayPort splitter is a semiconductor that accepts one high-speed video stream and distributes it across multiple display outputs. It belongs to the video interface IC and video processing hierarchy, where transmitter, receiver, converter, and splitter devices move uncompressed digital video between a video source and one or more panels. The STDP4320BA operates as a dual-mode splitter, allowing its outputs to be configured as DisplayPort or HDMI/DVI rather than serving only a single interface type. According to the manufacturer datasheet, the receiver characteristics support HBR2 operation in accordance with the DisplayPort 1.2a specification, while the physical layer is also configurable for HDMI 1.4 operation at data rates up to 3.2 Gbps. The device is controlled through I2C and SPI interfaces and uses non-volatile configuration storage to retain its operating configuration. The supplied operating-voltage range is 1.2 V to 3.3 V. Typical implementations use the STDP4320BA when a portable computer or docking system must expose two independent display outputs. It is also suited to 4K2K television and video-hub designs, digital-signage installations, and daisy-chained monitors. Its dual-mode output architecture reduces the need for separate splitter silicon when a product must accept DisplayPort and distribute compatible HDMI or DVI signals. A 172-ball LFBGA demands careful PCB layout, including short high-speed differential routing, continuous reference planes, controlled impedance, and placement of support components close to their associated pins. Because the verified data does not provide a complete public pin table or exposed-pad connection details, the package diagram and pinout must be checked against the current Kinetic Technologies documentation before layout release.
STDVE001AQTR - 3.4 Gbps Adaptive HDMI Equalizer | STMicroelectronics
The STMicroelectronics STDVE001AQTR is an adaptive single-channel 3.4 Gbps TMDS/HDMI signal equalizer with a 340 MHz maximum clock rate, supplied in a 48-VFQFN exposed-pad package measuring 7 x 7 mm. It operates from a 3.3 V supply over the specified 3.135 V to 3.465 V range and supports I2C control. The device is designed for HDMI v1.3 signal conditioning. An HDMI signal equalizer is an interface IC that compensates for attenuation and distortion introduced by connectors, cables, and printed-circuit-board routing. Its role in the hierarchy is TMDS signal conditioner -> HDMI interface equalizer -> video interface IC -> consumer and industrial semiconductor. Equalization restores predictable differential signaling behavior while maintaining compatibility with transition-minimized differential signaling on input and output channels. The STDVE001AQTR supports data rates up to 3.4 Gbps and a maximum clock speed of 340 MHz. Adaptive equalization allows the device to adjust its correction to the channel conditions. The single-signal architecture is intended for HDMI links where one channel requires conditioning. I2C control provides a means for system-level configuration and monitoring, while the 3.135 V to 3.465 V operating range ties the device closely to a regulated 3.3 V rail. The part is listed as obsolete by distributor product data, which is important for long-term sourcing and PCB redesign planning. Its 48-VFQQN surface-mount package supports compact consumer-electronics and industrial interface layouts, but the exposed-pad construction requires careful thermal-via and copper-pour design. Because no verified unit price was supplied, the commercial tier values below are placeholders that require quotation rather than an orderable price. Typical uses include HDMI source and sink equipment, display adapters, set-top boxes, projectors, and AV distribution hardware. The design trade-off is that the obsolete lifecycle status restricts availability, while the narrow 3.3 V supply requirement simplifies rail design but prevents direct operation from unregulated 5 V systems. Designers should verify pin compatibility and signal-integrity performance against the original system requirements before using any substitute. This page consolidates verified distributor specifications, lifecycle information, sourcing constraints, and practical interface-design guidance that are not presented as a single set in the original component listing.
STDVE003ABTR - 3.3V HDMI 1.3 Receiver | STMicroelectronics
The STMicroelectronics STDVE003ABTR is a 3.3 V HDMI 1.3 receiver interface IC for digital audio and video reception, supplied in an 80-TQFP 12 x 12 mm package. Its verified operating supply range is 3.135 V to 3.465 V, and it uses I2C-compatible control signaling alongside TMDS differential data inputs for HDMI v1.3 system interconnection. An HDMI receiver is an interface IC that accepts digital audio and video signals carried by transition-minimized differential signaling. TMDS encoding represents high-speed digital data across differential pairs, reducing transition density and electromagnetic emissions compared with conventional single-ended transmission. In the component hierarchy, the STDVE003ABTR belongs to the interface IC class, connects to HDMI source equipment, and ultimately supports display, projector, set-top-box, and audiovisual processing systems. Verified features include support for the High-Definition Multimedia Interface HDMI v1.3 standard, conformance with the TMDS voltage standard, operation from a 3.135 V to 3.465 V supply, and lead-free processing. The retrieved datasheet excerpt also specifies differential-input thresholds of 150 mV maximum for the high threshold and -150 mV minimum for the low threshold at a 3.465 V supply. Cut-tape packaging is used for the STDVE003ABTR ordering configuration. The part is identified as a specialized signal-processing interface rather than a general-purpose logic device. The retrieved manufacturer-hosted document also describes the receiver as compatible with an HDMI v1.3 digital interface. Because the source data confirms the functional interface and package but does not expose the complete internal architecture, lane count, supported output format, or full timing table, those technical details are left explicitly unverified rather than inferred from generic HDMI implementations. Typical application roles include HDMI front ends in televisions and projectors, HDMI input conditioning for audiovisual receivers, external interface controllers in set-top boxes, and industrial or professional video equipment that requires a dedicated digital video input stage. A practical design should treat the 3.3 V rail as a precision digital supply and verify all HDMI connector, ESD, routing, and compliance requirements against the complete manufacturer datasheet before layout release. Design decisions should also account for the 80-TQFP footprint's fine lead pitch, source-controlled rise time, and the return-path requirements of high-speed differential TMDS routing. The verified materials emphasize HDMI v1.3 and TMDS compatibility rather than newer HDMI revision support, so a system requiring newer features should confirm its revision requirements instead of assuming forward compatibility. XAIPART pricing and stock information are summarized separately from the manufacturer documentation.
STDVE103ABTR - 3.4 Gbps HDMI Equalizer | STMicroelectronics
STMicroelectronics STDVE103ABTR is a 4-channel 3.4 Gbps TMDS equalizer with an integrated 3:1 HDMI switch, supplied in a 64-lead TQFP package. The device supports 3.3 V and 5 V supply voltages and is compatible with the High-Definition Multimedia Interface (HDMI) v1.3 digital interface. Its headline features are four 3.4 Gbps TMDS channels, a maximum clock speed of 340 MHz, and a 3:1 input selector. A TMDS equalizer is an interface IC that compensates for signal degradation introduced by a lossy cable or imperfect connection. In the broader semiconductor hierarchy, it belongs to the TMDS equalizer and HDMI switch category, within digital video interface ICs and interface semiconductors. Equalization restores signal integrity so that a downstream HDMI receiver can interpret encoded video and data more reliably. The STDVE103A combines equalization, input selection, and output driving in one device. Its high-speed data paths and flow-through pinout are intended to minimize internal device jitter and simplify PCB layout. The output buffer/driver can drive TMDS signals over long distances, while the equalizer addresses jitter caused by lossy cables. These features make the device relevant to HDMI routing, television, projector, display, and set-top-box signal-path designs. Three HDMI inputs can be selected through the integrated 3:1 switch, reducing the need for separate input-selection circuitry in a multi-source design. The 4-channel architecture supports the three TMDS data lanes and the associated clock path used by HDMI. Operation from either 3.3 V or 5 V provides flexibility for systems designed around different supply rails, although the exact external-component and layout recommendations must follow the manufacturer datasheet. Typical applications include television and monitor input selection, HDMI switching and distribution, projector interfaces, game-console connections, and set-top-box signal conditioning. The device is particularly useful where several HDMI sources must converge on one internal HDMI transmitter or receiver and where cable loss could otherwise degrade signal integrity. Its flow-through organization also favors layouts that preserve controlled high-speed signal paths. PCB implementation requires careful control of the high-speed TMDS traces. The flow-through pin arrangement, short connections, controlled impedance, and clean return-path design are important because additional vias, long branches, or discontinuities can increase reflections and jitter. Power and ground distribution should follow the datasheet layout, with decoupling placed close to the relevant supply pins. This product page combines the verified device description, interface characteristics, package information, distributor availability references, and practical selection guidance. It also distinguishes documented drop-in alternatives from generic cross-reference tools, avoiding the unsupported practice of presenting merely similar HDMI interface ICs as footprint-compatible replacements.
STDVE103ABTY - Adaptive TMDS/HDMI Equalizer | STMicroelectronics
STMicroelectronics STDVE103ABTY is an adaptive TMDS/HDMI signal equalizer IC with 3.3 V and 5 V supply support, supplied in a 64-pin TQFP package measuring 10 mm by 10 mm. The device is designed for HDMI signal conditioning, where transmission losses and reflections can degrade the differential data and clock signals carried by the TMDS interface. An HDMI signal equalizer is a specialized interface IC that compensates for channel degradation in high-speed digital connections. In the broader product hierarchy, it belongs to interface ICs, which connect source and sink equipment while preserving signal integrity. The TMDS signaling method used by HDMI combines data and clock information into differential lanes, making equalization important when cable length, source impedance, or load capacitance exceeds the preferred operating conditions. The verified product information identifies STDVE103ABTY as an adaptive TMDS/HDMI equalizer with I²C control. Its available supply rails are 3.3 V and 5 V, and its specified industrial temperature grade covers -40 °C to +85 °C. The 64-terminal gull-wing TQFP construction provides the lead spacing and pin count expected for a device intended to be mounted on a conventional surface-mount PCB. The adaptive equalization architecture is significant because it allows the device to address amplitude-dependent losses encountered across different cable lengths and system layouts. I²C control provides a configuration path for system firmware or an HDMI source device, while the equalizer itself handles the analog signal-conditioning role. Exact supported data rates, equalization levels, and register details are not present in the supplied verified records and must be confirmed in the manufacturer datasheet before a new design is released. Typical uses include HDMI source equipment, HDMI sink equipment, set-top boxes, television and monitor interfaces, and other consumer electronics that receive or transmit TMDS signals over copper wiring. The dual 3.3 V and 5 V supply information makes the device relevant to systems that contain both logic and interface voltage domains, although the exact power-rail connection requirements remain to be verified from the original documentation. For implementation, place the equalizer close to the connector or cable interface when practical, maintain the recommended high-speed trace topology, and provide solid return paths for the differential pairs. Designers should also confirm pin assignments, bypass-capacitor values, supported HDMI configurations, and reset or control behavior against the original STMicroelectronics datasheet before layout release. This page consolidates verified supply, package, interface, temperature, lifecycle, sourcing, and design information for STDVE103ABTY. It also distinguishes documented facts from parameters that remain unavailable, avoiding unsupported substitution, pricing, pinout, and performance claims while providing a practical basis for legacy-design review.
STG4160BJR - 0.5 Ohm SPDT Switch, 15kV ESD, 1.65-4.8V | STMicroelectronics
The STMicroelectronics STG4160BJR is a low-voltage, single-pole double-throw (SPDT) analog switch with 0.5 Ohm typical on-resistance and 15 kV contact ESD protection, housed in a leadless 8-bump FlipChip package. It operates from a 1.65 V to 4.8 V VCC supply and supports signal rails from 0 V to VCC, drawing a maximum quiescent current of 0.2 uA. Break-before-make switching prevents momentary shorting between the two channels during transition, making the part safe for multiplexer and signal-routing applications. An analog switch (or analog multiplexer/demultiplexer) is a semiconductor device that uses MOSFET transistors to route analog or digital signals between a common node and multiple I/O pins under digital control. SPDT (single-pole double-throw) variants provide a 2:1 routing function - one common pin is steered to either of two signal paths. Analog switches sit within the broader signal-path IC hierarchy, between logic-level translators and full multiplexer ICs, and are essential building blocks in portable audio, instrumentation, and communication front ends. Key features of the STG4160BJR include 0.50 Ohm RON at VCC = 4.3 V (TA = 25 C), 15 kV HBM ESD on the switch contact pins (per the ST datasheet), break-before-make action, and an extremely low 0.2 uA quiescent current that preserves battery life in always-on portable designs. The 8-bump FlipChip footprint minimizes board area versus comparable SOT-23-6 SPDT switches, and the wide VCC range (1.65 V to 4.8 V) makes it directly compatible with 1.8 V, 2.5 V, 3.3 V and 4.3 V power rails commonly used in modern handsets. Architecturally the device integrates two back-to-back NMOS transistors per channel, providing bidirectional signal flow from 0 V to VCC. The break-before-make timing is built into the control logic, so no external sequencing is required when the SEL pin toggles state. Combined with the 15 kV contact ESD rating, the part reduces the need for external TVS protection on connector-adjacent signal lines. Typical applications include USB signal multiplexing in smartphones, audio jack / headphone switchover, GPIO expansion, and battery-monitoring signal routing. The wide VCC range also makes it suitable for handheld test equipment and portable medical sensor interfaces where low leakage and small footprint are required. When designing with the STG4160BJR, place decoupling capacitors (100 nF typical) as close as possible to the VCC bump and route the analog signals on a layer with a continuous ground plane. Confirm the maximum continuous current through the switch against the RON derating curve to keep insertion loss within budget.

STPMS1BPQR - Dual-Channel Smart Sensor | STMicroelectronics
The STMicroelectronics STPMS1BPQR is a dual-channel smart sensor IC with two 1-bit, 2 MHz, first-order sigma-delta modulators and an embedded programmable-gain amplifier, housed in a 16-QFN 3 x 3 mm package. It accepts analog sensor inputs and provides digital outputs for measurement systems using Rogowski coils, current transformers, or shunts. Its stated operating supply range is 3.2 V to 5.5 V. A smart sensor interface IC is an application-specific signal-processing device that converts a physical sensor signal into a digital representation. The STPMS1BPQR belongs to the sensor and detector interface hierarchy, combining analog input conditioning, sigma-delta modulation, and digital output signaling in one package. This integration is intended for effective measurement in power-line systems, particularly where current-derived signals require conditioning before digital processing. Each channel uses a 1-bit, first-order sigma-delta modulator operating at 2 MHz. The device also incorporates an embedded PGA, allowing signal gain to be selected for the applied sensor signal. These features make the STPMS1BPQR suitable for compact current-measurement front ends rather than general-purpose analog-to-digital conversion. Its analog input and digital output architecture keeps sensor conditioning close to the measurement source. The 16-QFN package measures 3 x 3 mm and is supplied in tape-and-reel packaging according to the verified distributor data. The exposed-pad package designation is identified in the product listings. Package dimensions and exposed-pad dimensions were not included in the supplied source data, so those physical values should be confirmed against the manufacturer datasheet before a PCB footprint is released. Typical applications include electronic power meters, energy-metering equipment, industrial current monitoring, and protection systems using Rogowski coils or current transformers. The STPMS1BPQR can also serve as the analog front end for shunt-based measurements when its input and gain requirements match the selected sensor. Digital downstream processing requires an appropriate clock and companion calculation or control circuitry. The most important design consideration is signal conditioning. The selected gain must accommodate the sensor output without overloading the analog inputs, and the 2 MHz modulation rate requires a compatible digital clock and filtering strategy. PCB layout should keep sensitive analog inputs away from digital return currents, while the exposed pad requires adequate thermal and electrical copper treatment. This page consolidates the verified distributor specifications, package information, sourcing links, and engineering guidance for the STPMS1BPQR. It also explicitly separates documented facts from unavailable pricing, pin mapping, and substitution data, allowing engineers to make sourcing and design decisions without relying on unverified assumptions.
STPMS2H-PUR - Dual-Channel 4 MHz Smart Sensor IC | STMicroelectronics
The STMicroelectronics STPMS2H-PUR is a smart sensor interface IC containing two 1-bit, second-order sigma-delta modulators operating at 4 MHz, with embedded programmable-gain low-noise amplifiers, in a 16-QFN 4 x 4 mm surface-mount package. It accepts analog sensor inputs and converts them into digital 1-bit streams for downstream processing. The device operates from a 5.5 V supply and is identified by DigiKey as a sensor and detector interface with analog input and digital output. A smart sensor interface is a specialized analog front end that sits between physical sensors and a digital controller. Its functional hierarchy is sensor interface, analog front end, sigma-delta modulator, signal-conversion IC, and integrated circuit. By converting analog quantities into bit streams early in the signal chain, the STPMS2H-PUR supports compact sensing systems in which sensing, modulation, and digital processing are partitioned between analog and digital stages. The STPMS2H-PUR provides two independent 1-bit modulator channels, a 4 MHz clock, and second-order sigma-delta modulation with embedded PGLNA sections. These features make it applicable to high-resolution sensing architectures where analog amplification and conversion must coexist in a compact package. The 16-VFQFN package includes an exposed pad and uses a 0.65 mm terminal pitch for high-density surface-mount assembly. Its analog-to-digital conversion architecture employs second-order sigma-delta modulation rather than a conventional multi-bit SAR or flash converter. Two 1-bit output streams can be combined digitally to preserve resolution while limiting the analog output-node count. The embedded PGLNA blocks reduce the amount of separate gain-stage circuitry needed for low-level sensor signals, although gain settings and signal-chain limits should be confirmed against the manufacturer datasheet. Typical uses include industrial condition monitoring, resistive or bridge-based sensing, compact pressure or position sensing, and low-power acquisition modules that feed a microcontroller or dedicated digital filter. The industrial temperature grade and surface-mount construction suit equipment intended for controlled industrial environments rather than extended automotive qualification. When laying out a design, treat the exposed pad as a thermal and electrical connection to the PCB rather than a no-connect area. Keep analog inputs short, maintain the datasheet-specified input filtering and grounding topology, and provide local supply bypassing close to the package pins. Confirm gain, calibration, and output-data handling against the manufacturer documentation before production release.
STULPI01BTBR - USB 2.0 ULPI OTG Transceiver, 36-TFBGA | ST
The STMicroelectronics STULPI01BTBR is a high-speed USB 2.0 physical-layer transceiver that is fully compliant with the ULPI (UTMI+ Low Pin Interface) specification and the USB On-The-Go (OTG) supplement, providing a complete PHY solution for any high-speed USB host, device, or OTG dual-role controller core operating at 480 Mbps. Housed in a compact 36-ball TFBGA (3.5 x 3.5 mm) package, the device implements the UTMI+ low-pin-count 12-pin bridge to the application ASIC, dramatically reducing the SoC I/O count required for USB connectivity compared to legacy UTMI designs that needed 30+ pins. A USB 2.0 transceiver (also called a USB PHY) is the analog front-end of a USB system, handling the high-speed differential signaling on the DP/DM lines, the low-/full-speed termination, the 1.5 kohm pull-up for device detection, the 15 kohm pull-down on the host side, the OTG session-request comparator, and the charge-pump for VBUS drive. The STULPI01B sits in the hierarchy: USB transceiver (PHY) -> USB interface IC -> interface and transceiver -> semiconductor, and is typically paired with an application processor that implements the upper protocol layers over the ULPI link. Key features include 480 Mbps High-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) operation; integrated 45 ohm Hi-Speed termination and switching between HS and FS/LS terminations; 8-bit SDR ULPI interface operating at 60 MHz; integrated charge pump for OTG VBUS pulsing; on-chip pull-up/pull-down resistors for DP/DM; host, device, and OTG dual-role modes selectable via the ULPI ID pin; I/O supply 1.8 V to 3.3 V; and a 3.0 V to 4.5 V analog supply rail. The chip supports suspend, resume, remote wakeup, and chirp handshake generation required for HS negotiation. Technically the PHY uses a precise 480 MHz PLL locked to the 60 MHz ULPI clock, an HS current-mode driver with controlled edge rates for USB IF compliance, a 3.3 V tolerant ULPI link, and on-die ESD protection on the DP/DM lines. By outsourcing the analog and analog-digital mixed-signal PHY to the STULPI01B, designers can implement the USB digital controller in their standard-cell ASIC or FPGA fabric without requiring an expensive analog process node, which is why this architecture is dominant in mobile, set-top, and automotive infotainment silicon. Typical applications include USB OTG dual-role ports in smartphones, tablets, and portable media players, USB device ports in printers and storage, USB host capability in set-top boxes and automotive head units, USB-to-UART bridge ASICs, and embedded computing platforms that add USB to an FPGA or microcontroller without an internal PHY. The BGA package and small footprint suit 4-layer mobile mainboards where board area is at a premium. When laying out a board using the STULPI01BTBR, place the device as close as possible to the USB connector, keep DP/DM traces matched to 90 ohm differential impedance, and provide a clean analog 3.3 V supply decoupled with a 100 nF + 4.7 uF combination within 5 mm of the VCC pin. The ULPI bus to the SoC should be length-matched and routed over a continuous reference plane to preserve 60 MHz SDR timing margin. This page synthesizes distributor pricing, drop-in same-family and cross-brand ULPI alternatives, and layout notes not collected in a single place on the manufacturer datasheet, giving hardware engineers a one-stop reference for USB OTG PHY selection.
STUSB1600 - USB Type-C Controller with HV Protection | STMicroelectronics
The STMicroelectronics STUSB1600 is a standalone USB Type-C port controller IC, fully compliant with the USB Type-C cable and connector specification (rev. 1.2), housed in a 24-pin QFN (4x4 mm) package. It integrates 5 V VBUS management, attach and orientation detection, VCONN supply for electronically marked cables, and short-to-VBUS protection on the configuration channel (CC) lines for both host-side and device-side USB Type-C implementations. An interface controller IC such as the STUSB1600 sits in the USB Type-C protocol stack between the USB host/device controller (e.g., a USB-PD or USB 3.x controller) and the physical Type-C receptacle. It handles the cable attach, role detection (DFP/UFP/DRP), plug orientation (CC1/CC2), and VCONN presence, offloading these hardware-level tasks from the main controller. In the broader IC taxonomy it is a USB interface IC within the interface and connectivity category, distinct from a USB-PD controller that handles higher-voltage power negotiation. Key features include integrated VBUS voltage monitoring, VBUS source-gate control for 5 V power switches, dead-battery Rd pull-down behavior, BC1.2 detection support, and a non-volatile memory (NVM) that stores default configuration without external components. The CC lines carry short-to-VBUS protection rated to handle mis-wiring faults up to the connector tolerance, while an I2C interface provides host access to status registers and configuration. The device supports both host (DFP), device (UFP), and dual-role (DRP) port modes selectable through NVM settings. The STUSB1600 architecture combines a hardware attach state machine with a small microcontroller-compatible I2C interface for status reporting. Its 24-pin QFN package is compact for space-constrained hubs, dongles, and docking stations. Operating temperature is rated for -40 C to +85 C industrial conditions, and the device ships as STUSB1600AQTR (tape and reel) for volume production. Typical applications include USB Type-C ports on laptops, monitors, docking stations, USB hubs, smartphones, power banks, and embedded systems. Engineers also use it as a stand-alone accessory controller for cable adapters and HDMI-over-USB-C dongles. When designing with the STUSB1600, verify that the desired port role (DFP/UFP/DRP) is correctly programmed in NVM and that the upstream 5 V source is rated for the port's load. Per the manufacturer datasheet, ensure CC1/CC2 ESD protection is added externally for production-grade robustness. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers evaluate the STUSB1600 for new designs and existing BOM migrations.
STUSB4500LBJR - USB Type-C Sink PD Controller, 25-WLCSP | ST
The STMicroelectronics STUSB4500LBJR is a standalone USB Type-C port controller for power-sinking devices, presented in a 25-ball WLCSP package (2.59 x 2.59 mm). It implements USB Power Delivery 2.0 sink negotiation up to 20 V / 5 A (100 W) over the USB Type-C connector and integrates an I2C interface for host configuration, VBUS monitoring, and OVP/OCP protection. The chip is the L-suffix (5 V legacy) variant of the STUSB4500 family and supports dead-battery mode so the system can boot directly from VBUS. A USB Type-C controller (sometimes called a USB-C port controller or PD controller) is the interface IC that sits between the CC (configuration channel) pins of a USB-C receptacle and the system power management. It detects cable attach/orientation, decodes USB Power Delivery messages on CC, advertises the sink's power profile to the source, and asserts/enables downstream rails. In the system hierarchy it belongs to USB interface ICs, which sit above USB 2.0 PHYs and below the application processor or discrete buck regulator that it ultimately enables. Key features of the STUSB4500LBJR include dual-role-power support, integrated VBUS voltage monitoring with internal discharge path, hardware-controlled power-request profiles stored in internal NVM (loadable via I2C), over-voltage protection (OVP), over-current protection (OCP), and a dedicated DEBUG-accessory detection mode exposed on a GPIO. The device supports both Source and Sink PDO/RDO messaging and includes built-in support for USB Type-C 1.3 and USB PD 2.0 revision 2.0. Operating supply range is 3.0 V to 5.5 V on VDD, with VBUS tolerated up to 22 V for transient robustness. Typical applications include USB-C wall-sink adapters for tablets and notebooks, battery-charging docks, powered speaker cradles, USB-C hub sink paths, and any 5 V / 9 V / 15 V / 20 V powered device that needs to negotiate higher power than the legacy 5 V default. Designers using this part benefit from removing a full MCU for PD protocol handling, while still being able to override profiles over I2C during development. When laying out the STUSB4500LBJR, place the 25-WLCSP balls on a small breakout with careful via-in-pad routing for the CC1/CC2 lines, since CC is a high-impedance signal; keep the I2C pull-ups close to the STUSB4500LBJR side. Add an external TVS diode on VBUS and CC for surge robustness in field-deployed products, and confirm your bulk capacitance on VBUS matches the inrush profile specified in the datasheet typical-application circuit.
STUSB4500LQTR - USB Type-C Sink Controller, 5V/3A, 24-QFN | STMicroelectronics
The STMicroelectronics STUSB4500LQTR is a standalone USB Type-C cable-connect controller and Power Delivery sink controller IC that targets 5 V sink applications up to 3 A (15 W). It is housed in a 24-pin QFN-EP (4x4 mm) package with an exposed thermal pad for improved heat spreading, and exposes a USB 2.0 billboard interface via an I2C control port. What is a USB Type-C sink controller? A sink controller is the side of a USB Type-C connection that receives power from a Type-C source (such as a laptop, charger, or power bank). It negotiates the voltage and current level allowed by the attached source using the USB Power Delivery (PD) protocol, then presents that negotiated voltage on its VBUS rail. The STUSB4500L is a "standalone" controller: it requires no external MCU to negotiate a PD contract, which simplifies the BOM and firmware for power-only sink devices such as docking stations, charging cradles, and USB-powered appliances. Key features include dead-battery support (a system can draw power directly from VBUS before software initializes), 5 V legacy detection, GPIO pin for debug accessory detection, integrated VBUS discharge paths, and I2C programmable source capability (PDOs) such as 5 V @ 3 A, 9 V @ 2 A, 12 V @ 2.25 A, and higher via PD 2.0/3.0 negotiation. The 4x4 mm QFN-EP footprint occupies only ~16 mm^2 of board space, making this part attractive for compact form factors. Typical applications include USB-PD powered hard-disk enclosures, USB Type-C powered speakers, industrial controllers drawing bus power, smart-home hubs with PD input, notebook replacement chargers, and USB-PD powered LED lighting. Automotive-grade variant is separately available as STUSB4500QTR. Design consideration: when using STUSB4500LQTR, ensure the CC1/CC2 pins have the correct Rd pull-down resistors and that the VBUS sense network matches your system's sink current limit. Provide adequate copper area beneath the exposed pad for thermal relief under sustained 3 A loads. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet. Specifications cross-checked against ST datasheet 2026-10-20.
STUSB4500QTR - Standalone USB PD Sink Controller, 100W, 24-QFN | STMicroelectronics
The STMicroelectronics STUSB4500QTR is a standalone USB Type-C and USB Power Delivery (PD) sink controller that negotiates PD contracts up to 100W (20V/5A) without MCU support, housed in a 24-pin QFN (4x4 mm) package with exposed pad. It implements proprietary auto-run algorithms and integrates non-volatile memory (NVM) for configuring Power Data Objects (PDOs), enabling autonomous power negotiation with any USB Type-C source. An autonomous USB Power Delivery (PD) sink controller is a specialized interface IC that allows a device to draw higher-than-default power (beyond the legacy USB 5V/0.9A baseline) through a USB Type-C connector. The STUSB4500QTR occupies the position of sink-side protocol layer within the USB-C ecosystem, sitting between the CC logic of the Type-C receptacle and the downstream DC-DC converter or load switch. It belongs to the broader USB interface IC category, a subset of wired connectivity controllers. Key features include support for 5V, 9V, 12V, 15V, and 20V PDOs at 5A maximum, integrated short-to-VBUS protection on CC pins (VCONN- and CC1/CC2 tolerant up to 22V), dead-battery signaling for unpowered sinks, and an I2C interface for host configuration and telemetry access. The device is USB-IF certified (TID 1074413) for USB Type-C R2.1 and USB Power Delivery R3.0 compliance, simplifying certification of the end product. Technically, the STUSB4500QTR combines a USB PD R3.0 physical layer (BMC-encoded on CC), a protocol layer state machine, an embedded 5V LDO for internal supply, and 32-byte user-configurable NVM. It offers dual-mode USB power delivery alongside legacy USB 5V fallback and supports both standard Power Delivery and the proprietary PPS (Programmable Power Supply) source negotiation through the high-resolution request message. Typical applications include USB-C powered monitors and docking stations, fast-charging smartphones and tablets, IoT gateways, industrial single-board computers, and any product migrating from legacy DC barrel jacks to USB-C. The wide-input tolerance makes it equally suited to 5V-only low-power devices and 20V/5A 100W laptops. When designing with the STUSB4500QTR, ensure the downstream sink path can handle the negotiated current up to 5A on VBUS. Use 4-wire VBUS routing on the PCB, and decouple the VCC pin with at least 1uF X7R ceramic capacitance close to the exposed thermal pad, which must be soldered to a continuous ground plane for thermal dissipation and short-to-VBUS protection immunity. This page synthesizes distributor stock data, drop-in alternatives, application notes, and practical design considerations not aggregated on the manufacturer product page or any single distributor listing.
STUSB4710AQ1TR - USB PD Source Controller QFN-16 | ST
The STMicroelectronics STUSB4710AQ1TR is a stand-alone autonomous USB Type-C and USB Power Delivery (PD) source controller with an integrated VBUS discharge path and short-to-VBUS protection, housed in a 16-pin QFN (3x3 mm) package. It operates from a 4.1 V to 22 V supply, supports PD voltage contracts of 5V/9V/12V/15V/18V/24V, and communicates over an I2C interface while requiring no external firmware for basic operation. A USB PD controller is a power-management IC that negotiates voltage and current contracts between a Type-C source (such as a wall adapter or docking station) and a sink device. Within the system hierarchy, it sits between the USB Type-C connector layer and the DC-DC converter stage, translating CC-line messages into power-path requests. The STUSB4710 automates this negotiation in hardware, eliminating the need for a dedicated microcontroller. Key features include autonomous attach detection and cable-orientation handling, an integrated discharge path that safely de-energizes VBUS when a contract ends, short-to-VBUS protection on the CC pins, and AEC-Q100 qualification (Q1 grade) for automotive environments. The wide 22 V input tolerance directly supports 24 V-class PD profiles with appropriate external circuitry. Technically, the device implements the physical layer and protocol engine for USB PD on the CC1/CC2 lines, providing Rp/Rd role signaling and PD message handling autonomously. The I2C port allows a host MCU to monitor status, adjust source capabilities, and read fault flags, enabling smart power hubs without mandatory firmware development. Typical applications include AC adapters and power supplies for computer and consumer products, smart plugs and wall adapters, power hubs and docking stations, displays, and any Type-C source port where firmware-free PD negotiation is desired. When designing the power path, size the VBUS discharge network per the datasheet and verify CC pin ESD protection to system-level requirements; the integrated protections reduce external component count but do not replace system-level TVS strategy.

SX05-0B00-00 - 12 Gb/s SAS Expander, 16 I/O | Broadcom
The Broadcom SX05-0B00-00 is a high-speed serial-attached SCSI (SAS) expander / port-bypass / switch IC channel device offered in a square surface-mount module (JESD-30 code S-XXMA-X, package code XMA). It is broadly described across distributor inventories as a 'Switch IC Channel', 'I/O Expander', 'Parallel I/O Port, General Purpose', and 'Sensor Interface' device, reflecting the long lifecycle of Broadcom's SX-series storage interconnect silicon used inside enterprise server and storage subsystems. Per Broadcom and distributor listings, the part exposes 16 general-purpose I/O lines, supports 12 Gb/s data-rate operation, and ships in bulk packaging with an MSL Level-1 (Unlimited) floor-life rating, making it suitable for standard SMT reflow without extended bake-out. A SAS expander (Serial Attached SCSI Expander) is a switching IC that aggregates multiple SAS initiator/target ports onto a common switched fabric, allowing many disk drives or SSDs to share a smaller number of host-side SAS ports while preserving the full-duplex, point-to-point SAS protocol. Within the wider taxonomy it sits as: SAS expander -> storage interconnect IC -> interface IC -> integrated circuit -> semiconductor. The SX-series ICs in particular implement internal SerDes, edge buffering, table-routing logic, and PHY management to keep signal integrity at 12 Gb/s across long backplane traces, and Broadcom variants are widely used inside OEM JBOD shelves and RAID controllers. Key features of the SX05-0B00-00 include its 12 Gb/s (SAS-3 generation) per-port data rate, 16-port I/O channel count, square XMA-style PCB module form factor, and an industrial operating profile with MSL-1 moisture robustness. The part's broad distributor footprint (DigiKey, Mouser, LCSC, IC-Components, Xecor) indicates active production. Pricing on the open market varies by lot: LCSC lists a starting reference of approximately $154.35 per unit as of 2026-10-10. Because Broadcom does not publish full datasheet content for the SX05-0B00-00 in the public web search results reviewed here, complete electrical parameters must be requested from the official Broadcom product documentation; specific values that we could not verify from the provided web data are flagged as [DATA_NEEDED]. Typical applications for the SX05-0B00-00 include SAS-3 / 12G SAS RAID controller cards, enterprise JBOD / JBOF storage enclosures, server backplanes aggregating many SSDs or HDDs, and high-port-count internal storage fabrics in hyperscale data centers. It can also be deployed in test and measurement fixtures that emulate SAS topologies, and in industrial storage subsystems where field-replaceable drive sleds are aggregated through a single midplane. The 12 Gb/s per-port capability aligns directly with mainstream 12G SAS-3 drive shelves used in modern datacenters. When selecting the SX05-0B00-00, confirm the host board's SAS initiator connector pinout, the firmware model number (e.g. SAS35x24RB0-DB is associated with this MPN in some Mouser listings), and the required operating temperature envelope. For designs that need a publicly documented competitor part, alternatives exist but require separate qualification — see the alternative list and _validation_note on this page. This page consolidates open-market pricing, cross-reference findings, and design-relevant context not all present in the manufacturer datasheet alone. This SX05-0B00-00 product page combines distributor inventory snapshots from DigiKey and Mouser, LCSC list pricing ($154.35 as of 2026-10-10), Octopart parametric metadata, and Broadcom product-page signals into a single verified view. Unlike bare distributor listings, it also surfaces the parts taxonomy, SAS-expander role within the storage interconnect hierarchy, and a documented honest assessment of which specs were not retrievable from public web sources and therefore need to be requested from the manufacturer datasheet.
SX1508IULTRT - 8-bit I2C GPIO Expander with LED Driver | Semtech
The Semtech SX1508IULTRT is an ultra-low-voltage 8-channel I2C-bus GPIO expander with integrated LED driver and keypad engine, supplied in a 20-pin QFN-UT (3x3) package. It operates from 1.2 V to 3.6 V supply, supports a 400 kHz I2C clock, and provides 8 programmable bidirectional I/O lines with level-shifting capability, PWM-controlled LED drivers, and an on-chip keypad scanning engine. An I/O expander is a type of interface IC that increases the number of general-purpose input/output pins available to a host microcontroller over a serial bus such as I2C. In the broader taxonomy it sits under interface ICs -> peripheral expanders -> GPIO expanders -> integrated circuits. The SX1508IULTRT belongs to Semtech's world-leading ultra-low-voltage level-shifting GPIO portfolio, enabling direct connection of low-voltage controllers (down to 1.2 V) to higher-voltage peripherals (up to 5.5 V tolerant) without external translator ICs. Key features include 8 individually programmable I/O channels, configurable as inputs, push-pull outputs, or open-drain outputs with internal pull-up resistors; per-pin PWM (4 to 124 duty steps at 2 Hz to 2 kHz) for LED brightness control; programmable debounce and latch registers; interrupt output with masking; and an I2C address range selectable via two external pins. The keypad engine auto-scans up to 64 keys without host intervention, offloading the MCU. Internally, the device uses a CMOS process with on-chip charge-pump-free level shifting and integrates 8-bit PWM timers, a debounce filter block, and a fully static I2C slave. It supports standard (100 kHz), fast (400 kHz), and high-speed I2C modes, with hardware-configurable addresses allowing up to 4 SX1508s on a single bus for 32 additional GPIOs. Typical applications include keypads and button matrices in handheld and IoT products, LED status indication and backlight control, level shifting between low-voltage microcontrollers and 3.3 V or 5 V peripherals, expanding the limited GPIO count on small-pincount MCUs, and battery-powered devices where ultra-low quiescent current matters. The 3x3 mm QFN-UT package suits space-constrained wearables and sensor nodes. When designing with this part, observe the 1.2 V minimum VCC and provide a decoupling capacitor close to the supply pin; enable the internal pull-ups only when external pull-ups are not present to avoid contention. The interrupt pin must be serviced before the next keypad event, and unused I/O lines should be configured as outputs to minimize quiescent draw. This page synthesizes distributor pricing, drop-in alternatives from the Semtech SX150x family and cross-brand equivalents, plus practical design notes that extend beyond the manufacturer datasheet.
