DP8304BWM 개요
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.

일반적인 애플리케이션
DP8304BWM 적합 용도: 6 애플리케이션s: 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.
추천
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.
추천
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.
추천
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.
추천
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.
추천
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.

주요 차별점

설계 노트
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.
규정 준수 정보
The supplied verified results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status.
