DP8308N Übersicht
A bidirectional bus transceiver is a logic-interface IC that combines driver and receiver functions on each signal line. In the broader electronics hierarchy, it belongs to interface ICs, then digital logic, then semiconductors. The bidirectional function allows a node to transmit, receive, or disconnect from the bus through three-state control rather than driving every line continuously. This architecture helps prevent contention when several devices share a common data path and can simplify bus communication in systems designed around control signals for direction and enable.
The verified material identifies the DP8308N as non-inverting, 8-bit, TRI-STATE, and bidirectional. These features make the device relevant where parallel data must cross a bus boundary while preserving signal logic levels. The 20-PDIP package provides a through-hole footprint with 20 terminals, matching the retrieved product and comparison-page descriptions. Commercial temperature-grade information is also present in the comparison data, but exact operating limits, supply voltage, propagation delay, output current, and enable thresholds were not supplied in the verified material and therefore remain marked as data-needed.
Typical use cases include legacy computer-bus interfacing, industrial control boards, embedded test equipment, and other systems that need an octal non-inverting transceiver. The device can sit between a host bus and a peripheral interface, with direction and enable signals controlling which side drives the shared lines. Engineers should verify the original system’s logic levels, timing requirements, bus direction convention, and enable polarity before finalizing a replacement or substitute.
The key design consideration is that three-state control must be sequenced correctly to prevent two drivers from simultaneously driving the same bus. Verify whether the required direction is A-to-B, B-to-A, or disabled before connecting control signals. Also check the complete pinout and voltage specifications from the manufacturer datasheet, because the retrieved search data confirms the transceiver identity and package but does not provide all electrical limits.
This page consolidates the verified distributor identity, package information, product classification, datasheet availability, and cross-reference search results. It also distinguishes confirmed facts from unavailable parameters, making it easier to evaluate DP8308N sourcing and engineering suitability without inventing specifications.

Typische Anwendungen
DP8308N ist geeignet für 6 Anwendungs: Legacy Parallel Computer Bus, Industrial Control Backplane, Test and Measurement Equipment, Embedded Processor Data Port, Peripheral Bus Isolation, Educational and Retrofit Electronics.
Legacy Parallel Computer Bus
DP8308N fits a legacy parallel-bus interface when the system needs an 8-bit non-inverting path with controlled three-state operation. The transceiver can isolate a bus segment during disabled intervals, allowing multiple nodes to share conductors when direction and enable sequencing are correct. Its 20-PDIP through-hole package is useful for repair and industrial retrofit boards that are not constrained to surface-mount assembly. Before using it, verify the original bus voltage, timing budget, enable polarity, and per-line loading from the manufacturer datasheet.
Empfohlen
Industrial Control Backplane
The octal non-inverting architecture of DP8308N can support data exchange between a controller and a peripheral card in a through-hole control backplane. TRI-STATE capability helps a node disconnect from shared lines when it is not the active bus master, while the bidirectional path allows the same wiring to support both transmit and receive operation. The verified source identifies a commercial temperature grade, but the engineer must confirm the numeric temperature range, supply voltage, and timing before selecting it for production equipment.
Empfohlen
Test and Measurement Equipment
DP8308N can be used in older test and measurement instruments that distribute parallel command or status data across a controlled bus. Its eight bidirectional channels and non-inverting logic preserve the intended signal direction, while the three-state function can reduce contention during instrument handshakes. The 20-PDIP package favors repairable and expandable instrument platforms. Designers should account for signal-integrity margin, cable loading, grounding, and the exact enable timing rather than assuming that every bus transceiver has interchangeable control timing.
Empfohlen
Embedded Processor Data Port
A DP8308N interface can connect an eight-bit external data bus to a processor board when legacy logic levels and timing are acceptable. The bidirectional transceiver helps the port receive processor data and drive a peripheral bus without maintaining a permanent active output on every line. Through-hole construction is advantageous for prototypes, repair-oriented products, and industrial controllers assembled with conventional DIP sockets. The designer must verify processor voltage compatibility, direction-control mapping, setup and hold times, and maximum bus capacitance before release.
Empfohlen
Peripheral Bus Isolation
DP8308N is suitable for placing a controlled interface between two sections of a parallel peripheral bus, provided its verified electrical limits meet the system requirements. Disabled three-state outputs can isolate a segment during test, reset, or arbitration, reducing unintended bus loading. The non-inverting relationship simplifies logic when the surrounding devices expect the same data polarity in both directions. Validation should include worst-case driver contention, power-up states, control-signal defaults, and the timing relationship between enable and data changes.
Empfohlen
Educational and Retrofit Electronics
The through-hole DP8308N package is convenient for educational trainers, laboratory interfaces, and retrofit projects that use older parallel-bus architectures. The eight-bit bidirectional structure makes bus wiring and direction-control experiments accessible while retaining a conventional 20-pin DIP footprint. Because the supplied search results do not provide complete electrical limits, instructors and hobby engineers should use the datasheet to verify supply voltage, logic thresholds, timing, and maximum load before connecting modern processors or peripherals.

Wichtigste Unterscheidungsmerkmale
- Confirmed 8-bit non-inverting bidirectional organization (vs. DP8308)
- Through-hole 20-PDIP implementation (vs. DP8308N/A+)
- Commercial-grade legacy-interface positioning (vs. DP8212N)
Designhinweise
Do not connect or substitute the DP8308N until the complete 20-pin enable and direction mapping has been verified from the manufacturer datasheet. Bidirectional transceivers can place multiple drivers on one bus if control timing is wrong. Confirm whether the A and B sides have separate direction inputs, whether enable is active high or low, and what state occurs during power-up before applying signals.
The verified package is a 20-PDIP through-hole package. Preserve the original pin spacing, socket orientation, and pin-1 marking when creating a replacement board or adapter. Place decoupling and any required termination close to the transceiver and follow the manufacturer’s recommended layout. Because the supplied data does not include voltage, current, or timing values, do not infer capacitor values or termination from generic bus guidelines.
Treat DP8308N as a legacy parallel-bus device and validate signal integrity at the intended clock or transfer rate. Check rise and fall time, setup and hold timing, bus capacitance, line termination, and the number of enabled drivers using the datasheet and the complete system timing budget. The three-state feature reduces contention only when enable and direction controls are sequenced correctly; it does not by itself guarantee clean signal integrity.
Compliance-Informationen
The supplied search results identify DP8308N as a commercial-grade National Semiconductor bus transceiver but do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. No compliance claim is inferred.
