MC33990D - Technical Component Data | NXP Semiconductors
部品番号: MC33990D ✗ 生産終了MC33990D 概要
What is an Interface IC? An Interface IC is a semiconductor in the interface IC category that converts, conditions, buffers, or controls signals between a host processor and external equipment. Interface ICs can support communication buses, isolation functions, level conversion, transceivers, voltage references, and protocol-specific links. Because MC33990D interface, electrical, timing, and package details are unavailable in the supplied evidence, selecting it for a specific bus, voltage domain, data rate, automotive environment, or PCB land pattern would otherwise risk an invalid design assumption.
The principal verified limitation is data completeness rather than a confirmed technical weakness. The only usable identifiers are the MPN MC33990D, the NXP Semiconductors brand assignment, and the 2026-10-29 retrieval date. No manufacturer datasheet URL, package designation, pin map, absolute maximum ratings, recommended operating conditions, electrical characteristics, timing values, environmental ratings, qualification status, or lifecycle classification appears in the provided records. Those parameters therefore remain explicitly unresolved rather than being populated from memory or a non-verified secondary listing.
Typical use cannot be validated from the supplied evidence, so this page does not claim that MC33990D is intended for automotive networking, industrial control, communications, or another specific application. Engineers should first confirm the exact function, package drawing, pin-compatible land pattern, operating limits, and ordering configuration from the current NXP documentation. The empty alternative list is intentional because the supplied cross-reference search returned no results; proposing an MPN as pin-to-pin compatible without a verified package and parameter comparison would be misleading.
The key design consideration is to avoid treating the absence of retrieved specifications as evidence of universal applicability. Verify the manufacturer datasheet, errata, package information, lifecycle status, and qualification markings before schematic capture or PCB layout. Check every pin name, exposed-pad requirement, recommended decoupling, electrical limits, and timing condition against the exact ordering code. Obtain written lifecycle confirmation when production continuity matters.
This page uniquely separates verified identifiers from unverified technical assumptions and exposes every unresolved field. It also records the failed retrieval timestamp, the absence of usable source URLs, and the reason no drop-in alternatives, complete pinout, safe operating area, package drawing, or price tiers can be authenticated. That transparency gives procurement and engineering teams a reliable evidence boundary while directing them to the current manufacturer documents for procurement and design release.

主な用途
MC33990D の用途: 6 件s: Industrial Communication Interface, Automotive Network Interface, Controller-to-Bus Communication, Data Acquisition and Sensor Interface, Test and Measurement Equipment, General Embedded System Interface.
Industrial Communication Interface
MC33990D may be relevant to an industrial communication interface only if its verified NXP documentation confirms the required bus, voltage domains, timing, isolation, and environmental ratings. The supplied 2026-10-29 record does not provide those specifications, so no claim is made that the device supports a particular protocol or data rate. Before selecting it, compare the current datasheet against the controller and transceiver requirements, including propagation delay, fault behavior, ESD tolerance, and operating temperature. Verify the exact package and pinout before PCB allocation. An authorized distributor quotation should accompany the technical review, while lifecycle status must come directly from NXP because the available dataset does not establish it.
おすすめ
Automotive Network Interface
MC33990D should not be assigned to an automotive network design without verified evidence for its communication standard, operating voltage, ESD performance, temperature range, and AEC-Q100 status. None of those attributes is present in the supplied dataset, which failed on 2026-10-29 and returned no manufacturer records. A released automotive design must use the exact ordering code and current qualification documentation, then validate transient immunity, fault detection, bus loading, and sleep or wake behavior against system requirements. The package drawing and exposed-pad requirements must also be confirmed before layout. Until those checks are complete, treat any automotive suitability claim as unverified.
おすすめ
Controller-to-Bus Communication
A controller-to-bus communication design is a possible application for MC33990D, but the supplied evidence does not identify its supported protocol, electrical signaling, maximum data rate, or receive and transmit thresholds. Engineers must first retrieve the current NXP datasheet and compare those parameters with the host controller, bus topology, cable length, termination method, and system timing budget. Also review dominant-state behavior, loopback capability, fault flags, and supply sequencing. MC33990D must not be selected merely because it is categorized as an Interface IC. The exact package, pin assignments, and decoupling requirements must come from authenticated manufacturer documentation before schematic and PCB release.
おすすめ
Data Acquisition and Sensor Interface
MC33990D could be considered for a data-acquisition interface only after its verified input and output characteristics have been matched to the sensor path. The available record supplies no signal bandwidth, logic thresholds, isolation rating, noise performance, common-mode range, or power requirements. Those missing values are essential when converting or conditioning external sensor signals. Review the manufacturer's recommended application circuit, input filtering, reference arrangement, and grounding guidance. Confirm that the selected package can dissipate the required load and that all pins are compatible with the intended signal flow. Because the 2026-10-29 retrieval produced no technical records, no definite sensor-interface function is attributed to MC33990D here.
おすすめ
Test and Measurement Equipment
For test and measurement equipment, MC33990D would need verified timing, noise, supply, and reliability characteristics before it could be considered for a signal path. The supplied evidence does not provide these values, and no reference design or manufacturer application note was returned. A measurement design should verify input bandwidth, channel timing, settling behavior, common-mode range, isolation strategy, and calibration stability from the current datasheet. The device's status must also be checked with NXP because production continuity affects long-lived test equipment. Do not use this record to approve a schematic, and do not infer low-noise or high-speed performance from the part number. Obtain the official package drawing and errata together with the datasheet.
おすすめ
General Embedded System Interface
An embedded-system interface is the broadest possible use case suggested by the catalog category, but MC33990D cannot yet be assigned to a specific embedded application because its verified function and electrical limits are absent. The 2026-10-29 research record contains only the MPN and a failed-search notice. Before using the device, retrieve the NXP datasheet and confirm interface direction, logic compatibility, supply sequencing, signal timing, package footprint, and thermal requirements. Review whether a host MCU or DSP can meet the timing and enable requirements without added level shifting. If those requirements cannot be established, select an alternative whose complete datasheet supports the architecture. This page avoids presenting a generic category association as proof of applicability.

設計ノート
Do not authorize schematic release based on the MC33990D part number alone. The 2026-10-29 retrieval did not provide a datasheet, package drawing, or pinout, so supply domains, logic levels, timing, and exposed-pad requirements remain unknown. Download the current NXP documentation for the exact ordering code, check its revision and errata, and compare every connection against the manufacturer pin table. The D package suffix must not be interpreted as a verified footprint without the official package drawing.
Power-supply design cannot be finalized until the recommended input voltage, supply-current behavior, quiescent current, and absolute maximum ratings are verified. The supplied data contains none of these electrical values, and zero tier prices are placeholders rather than commercial quotations. Review power sequencing, current transients, decoupling, and exposed-pad grounding in the manufacturer guidance. Use measured or manufacturer-specified limits rather than assumptions, and confirm the thermal design after the package and electrical data are available.
Do not start a PCB layout until the exact package dimensions, land pattern, pin numbering, and thermal-pad configuration are available from an authenticated NXP drawing. Because the package and pin count are unresolved, a board footprint would carry avoidable assembly risk. Verify top-view orientation, pin 1 location, courtyard limits, solder-mask details, and whether a thermal pad requires solder and copper. Prototype only after the manufacturer footprint has been checked against the selected assembly process.
A cross-brand or same-family part cannot be called a drop-in replacement without verified package and pin compatibility. The supplied substitute search returned zero results, and no original pinout was available. A future candidate should be checked for footprint, pin names, logic thresholds, voltage domains, timing, ESD rating, temperature range, and qualification. Packaging or reel-code suffixes alone do not constitute distinct alternatives, and functional equivalents requiring PCB changes must not be represented as drop-in parts.
コンプライアンス情報
No compliance declarations or qualification records were included in the supplied evidence. The 2026-10-29 search returned no usable result records, so every compliance field remains unknown pending current manufacturer documentation.
