DP8304BWM 概要

The Texas Instruments DP8304BWM is an 8-bit tri-state bidirectional bus transceiver packaged in a 20-pin SOP. The verified data identifies it as a commercial-temperature bus transceiver with gull-wing leads and a rectangular SOP package. Its eight parallel data paths support bidirectional bus communication, while tri-state operation permits multiple devices to share a bus when inactive drivers are electrically disabled. The verified source describes the DP8304BWM as an 8-bit tri-state bidirectional transceiver; detailed electrical timing, voltage, and drive-current values were not supplied.

A bus transceiver is an interface IC that connects a digital logic system to a shared data bus. Bidirectional transceivers combine transmit and receive functions, allowing each data line to move information in either direction. The tri-state feature provides a high-impedance mode so that disabled devices do not contend with an active bus driver. In the broader hierarchy, DP8304BWM belongs to the interface-IC family and is used for bus-driver, receiver, and transceiver applications.

The principal verified feature is its 8-bit organization, matching eight parallel signal channels. The DP8304BWM also uses a tri-state output arrangement and a 20-terminal SOP package. Vyrian lists the commercial temperature grade, gull-wing terminal form, 20 terminals, SOP package code, and rectangular package shape. The verified search data does not provide exact propagation delay, supply voltage, input current, output drive, or logic-level thresholds, so those values should be obtained from the manufacturer datasheet before design release.

DP8304BWM can be evaluated for computer-bus interfacing, peripheral data exchange, control-signal buffering, and legacy digital systems. Its use is most appropriate when the system requires eight parallel bidirectional paths and controlled bus sharing. Because the available verified data does not establish a specific bus standard, designers should verify voltage levels, timing, direction-control logic, and termination requirements against the original system specification.

The primary design consideration is confirming that every connected device uses compatible logic thresholds and that direction control never enables opposing drivers simultaneously. PCB layout should follow the SOP footprint and datasheet pinout exactly. Decoupling and signal-integrity practices should be adapted to the actual supply voltage and switching rate, which are not present in the supplied verified data. Do not infer a replacement from package similarity alone.

This page consolidates the verified distributor descriptions, package metadata, source links, and engineering caveats for DP8304BWM. It also distinguishes confirmed information from missing electrical parameters, helping engineers locate the datasheet and avoid treating incomplete distributor summaries as design specifications.

主な用途

DP8304BWM の用途: 6 件s: Eight-Bit Parallel Computer Bus, Peripheral Data Exchange, Industrial Control Signal Buffering, Legacy Processor Bus Interface, Test and Measurement Backplane, Data Acquisition and Control Modules.

🖥️

Eight-Bit Parallel Computer Bus

DP8304BWM fits an eight-channel parallel bus interface because the verified part description specifies eight bidirectional tri-state channels. It can serve as the bus-facing transceiver between a controller and shared data lines when the system requires controlled direction changes and high-impedance release. The verified data does not specify supply voltage, propagation delay, or drive current, so the design must confirm those values against the bus specification. Validate timing at the actual load capacitance and ensure that only one compatible driver is enabled at a time.

🔧

Peripheral Data Exchange

DP8304BWM can be considered for parallel peripheral data exchange where eight data lines must move information in either direction. Its bidirectional tri-state organization allows a peripheral interface to connect to a shared bus while presenting a high-impedance state when it is not selected. Because the supplied data identifies only the channel count and bus-transceiver function, designers must verify voltage thresholds, timing, and pin-level enable logic in the manufacturer datasheet before using the part in a new peripheral design.

🏭

Industrial Control Signal Buffering

DP8304BWM may support older industrial control equipment that uses eight parallel control or status lines. Bidirectional operation can simplify shared backplane communication, while tri-state behavior helps isolate inactive nodes. The verified listing marks the part as commercial grade, but it does not provide an operating-temperature range, supply voltage, or isolation rating. Therefore, use it only for non-isolated, electrically compatible legacy control buses and verify environmental requirements separately.

⚙️

Legacy Processor Bus Interface

DP8304BWM is a candidate for legacy processor systems that require an eight-bit bidirectional bus transceiver rather than a modern serial interface. Its 20-terminal SOP package and gull-wing lead description support examination of older through-hole and leaded PCB designs. Exact pin functions and timing were not supplied in the verified data, so engineers must compare the official pinout and electrical tables with the original processor bus before approving a replacement or redesign.

🧪

Test and Measurement Backplane

DP8304BWM can be evaluated for a legacy test-system backplane that transports eight parallel command or response lines between instruments and a controller. Tri-state outputs are useful when multiple modules share a bus, but the actual receiver and driver thresholds must match the system. The supplied data does not confirm instrumentation input impedance, noise performance, or timing margins, so bench validation and signal-integrity review are required before deployment.

📡

Data Acquisition and Control Modules

DP8304BWM may be used in a compact data-acquisition or control module that needs eight bidirectional digital lines alongside analog measurement circuitry. The transceiver provides a defined way to interface digital control/status signals, but it does not replace analog front ends, isolation, or level translation. Verify the device’s logic voltage and timing against the module’s processor, and account for bus capacitance and signal reflections in the PCB layout.

What is DP8304BWM?
DP8304BWM is an 8-bit tri-state bidirectional bus transceiver from National Semiconductor, now associated with Texas Instruments in the verified data. It provides eight parallel data channels and is identified as a bus transceiver in the source listings. The verified package description is a 20-terminal SOP with gull-wing leads, commercial temperature grade, and rectangular shape. Electrical timing and voltage specifications were not included in the supplied search data, so the manufacturer datasheet should be used for final design decisions.
What is the operating voltage of DP8304BWM?
The supplied verified web data does not state the DP8304BWM operating or supply voltage. It confirms only that the device is an 8-bit tri-state bidirectional transceiver in a 20-terminal SOP package. Engineers should consult the manufacturer datasheet for the supported supply range and input thresholds before connecting the part to a bus. Do not infer a voltage from the DP8304 family name or from another device with a similar description.
Is DP8304BWM a tri-state device?
Yes, DP8304BWM is explicitly described as an 8-bit tri-state bidirectional transceiver. Tri-state operation allows an inactive device to place its outputs in a high-impedance state so that it does not contend with another active bus driver. The verified listing does not identify a separate enable-pin number, so control logic and exact electrical behavior must be confirmed from the datasheet. System designers should also verify that direction control prevents simultaneous opposing drive.
What package does DP8304BWM use?
DP8304BWM uses a 20-terminal SOP package with gull-wing leads and a rectangular package shape, according to Vyrian and Partstack listings. The verified results identify the package code as SOP and the terminal count as 20. The supplied data does not include dimensions or a land pattern, so PCB placement must follow the official package drawing. Package family equivalence alone is not sufficient to approve a substitute.
Where can I download the DP8304BWM datasheet PDF?
The DP8304BWM datasheet is linked from the verified AllDataSheet result at https://www.alldatasheet.com/datasheet-pdf/pdf/102205/NSC/DP8304BWM.html. The search result identifies the document as a DP8304BWM datasheet from National Semiconductor (TI), and another result reports a five-page document. Because the supplied data does not provide an official manufacturer PDF URL or a verified document number, use the linked datasheet cautiously and confirm all parameters before design use.
Where can I find the DP8304BWM pinout?
The verified web results identify the part and its 20-terminal SOP package but do not publish the complete pin-number mapping in the supplied text. Use the DP8304BWM datasheet or the package diagram associated with that document to locate the exact pinout. The selected package library key is soic-20 because the verified result states SOP with 20 terminals, but pin names and enable/direction assignments remain data-needed rather than guessed.
Is DP8304BWM currently in stock?
The verified Octopart India result reports stock of 48,910 pieces updated on October 14, 2024, but the supplied data does not establish current inventory for October 22, 2026. Availability should therefore be checked with an authorized distributor before ordering. This product page treats stock as unconfirmed and uses BackOrder structured-data availability rather than claiming in-stock status. Distributor listings can change independently of manufacturer lifecycle status.
Where can I buy DP8304BWM online?
DP8304BWM can be located through the verified DigiKey Marketplace result and the Octopart part-search result. The supplied data does not provide a current unit price, seller inventory, or guaranteed lead time, so online availability must be confirmed at the distributor. The verified sources include https://www.digikey.com/en/products/detail/rochester-electronics-llc/DP8304BWM/12106223 and https://octopart.com/part/national-semiconductor/DP8304BWM. Use an authorized source for production procurement.
What is the price of DP8304BWM?
A current DP8304BWM price is not included in the verified web data, so no numeric price is asserted here. The Octopart result says that pricing can be compared across three distributors, while other distributor pages provide product or cross-reference links without a confirmed quotation. Request a current quote before purchasing. Any price used in a commercial decision must be checked against the distributor on the transaction date.
What is the lead time for DP8304BWM?
The verified data does not provide a current manufacturer or distributor lead time for DP8304BWM. The Octopart result provides a marketplace search path, but it does not establish a guaranteed delivery date. Because lifecycle status is also not confirmed, engineers should obtain written availability and lead-time information from an authorized distributor. Do not use the October 14, 2024 stock snapshot as proof of present inventory.
Is DP8304BWM suitable for an 8-bit parallel bus?
DP8304BWM is structurally suited to an 8-bit parallel bus because the verified description specifies eight tri-state bidirectional channels. Suitability still depends on matching the bus voltage, logic thresholds, timing, direction-control scheme, and termination requirements. Those electrical parameters are not supplied in the verified search results, so confirm them in the manufacturer datasheet. The device should be treated as a candidate only after system-level timing and signal-integrity checks.
Can a different SOP-20 bus transceiver replace DP8304BWM?
A candidate replacement must match the complete DP8304BWM pinout, electrical levels, direction-control behavior, timing, and bus-load capability; an SOP-20 outline alone is insufficient. The supplied cross-reference results did not identify a verified drop-in substitute, so no alternative is listed. Do not substitute a mechanically similar bus transceiver without manufacturer pinout and parameter comparison.
What is the difference between DP8304BWM and a tri-state logic buffer?
DP8304BWM is an 8-bit bidirectional bus transceiver, whereas a tri-state logic buffer is normally a unidirectional or fixed-direction device. The verified DP8304BWM description explicitly identifies bus-transceiver functionality, eight channels, bidirectional operation, and tri-state behavior. The supplied data does not state propagation delay, supply voltage, or drive strength, so a detailed performance comparison requires the manufacturer datasheet.
What can replace DP8304BWM?
No verified drop-in replacement for DP8304BWM was present in the supplied Alternatives Cross-Reference Data. The search results point to generic cross-reference tools and a DP8304 family comparison, but they do not establish a pin-to-pin equivalent with quantified electrical matching. The correct next step is to compare candidate SOP-20 bus transceivers against the official DP8304BWM pinout and timing table.
What are the key specifications of DP8304BWM?
The verified key specifications are 8-bit organization, bidirectional operation, tri-state operation, commercial temperature grade, 20 terminals, gull-wing leads, SOP package code, and rectangular package shape. The verified source describes DP8304BWM as a bus transceiver. Supply voltage, propagation delay, output drive, logic thresholds, and operating temperature range are not included in the supplied data and must be obtained from the manufacturer datasheet before schematic or layout approval.
Is DP8304BWM active, obsolete, or discontinued?
The supplied verified web data does not provide a current manufacturer lifecycle designation for DP8304BWM, so its lifecycle status is recorded as unknown. The product appears in distributor and search listings, but that does not prove active production status. Check the current Texas Instruments product page, authorized distributor inventory, and lifecycle notices before committing to a new design or sole-source procurement.
How should DP8304BWM be used in a bidirectional bus design?
Use DP8304BWM only after confirming its official direction-control and enable functions, because the supplied verified text does not provide the complete pin mapping. Connect the eight bus channels according to the datasheet, ensure only one compatible driver actively sources each bus at a time, and place the inactive device in its specified high-impedance state. Validate propagation delay, setup/hold timing, signal levels, and termination with the actual bus load.

エンジニアリング参考データ: DP8304BWM — 比較、設計ガイダンス、コンプライアンス情報。

選定ガイド

Choose DP8304BWM when the design specifically requires the verified 8-bit bidirectional tri-state bus-transceiver function and a 20-terminal SOP package. Before committing, obtain the manufacturer datasheet and verify supply voltage, logic thresholds, propagation delay, enable or direction pins, output drive, and temperature limits. The supplied data does not confirm that any listed family variant is a true drop-in replacement, so treat the alternatives list as candidate references rather than approved substitutions. DP8304BNB in particular is listed as DIP-20 in the supplied comparison result and may not fit the same PCB. For a new design, compare modern interface ICs only after checking voltage, timing, bus direction, and environmental requirements; for a legacy repair, match the original pinout and electrical table before procurement.

主な差別化要因

  • Exact eight-channel bidirectional tri-state function (vs DP8304BWB)
  • Commercial 20-terminal SOP identity (vs DP8304BNB)
  • Clearer source metadata for the exact ordered suffix (vs DP8304N)

設計ノート

Do not approve a replacement based only on the SOP-20 outline or the phrase bus transceiver. The verified data does not provide the complete pinout, supply voltage, direction-control mapping, or timing values. Compare the official DP8304BWM pinout and electrical tables against the incumbent device, and specifically check that every data channel has the same direction and enable behavior. A mechanically similar part can still fail because of logic-level, timing, or drive-strength incompatibility.

Treat the eight data lines as a parallel bus and verify edge rate, propagation delay, setup/hold margin, and capacitive loading against the actual board. The supplied verified text confirms eight bidirectional tri-state channels but supplies no timing values, so do not estimate them from the package or family name. Keep the transceiver and bus-routing geometry consistent, provide the required return path, and validate ringing and contention with an oscilloscope before production release.

Use the official 20-terminal SOP footprint and pin numbering rather than inferring positions from the family comparison result. The supplied results confirm 20 terminals and gull-wing leads, while the exact pin functions remain unavailable. Preserve solderable lead access and avoid placing tall or heat-sensitive components near the leads. Because the complete pinout is not provided, do not finalize the layout until it has been checked against the manufacturer datasheet.

Confirm the DP8304BWM supply voltage and input thresholds from the manufacturer datasheet before adding decoupling or selecting level-shifting devices. The verified data does not state a supply range, quiescent current, or output-drive capability. In a legacy bus design, supply sequencing and signal-level mismatch can create false data or bus contention even when the package and channel count match. Apply the datasheet’s specified bypass and layout requirements once those values are confirmed.
