DP8308N 개요

National Semiconductor DP8308N is an 8-bit non-inverting TRI-STATE bidirectional bus transceiver with 8 bits per element, supplied in a 20-PDIP package. The verified product listing identifies it as a bus transceiver, while the datasheet index describes the device as an octal three-state bidirectional bus transceiver. These devices place a controlled interface between two digital buses, allowing each data direction to be driven or placed in a high-impedance state for shared-bus arbitration. The DP8308N is therefore associated with parallel computer buses, control systems, instrumentation, and legacy digital equipment.

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.

🖥️

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.

🏭

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.

🔧

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.

🔌

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.

🔗

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.

🧩

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.

What is DP8308N?
DP8308N is a National Semiconductor 8-bit non-inverting TRI-STATE bidirectional bus transceiver. According to the verified DigiKey result, it is a 1-element, 8-bit-per-element transceiver in a 20-PDIP package, while the verified datasheet index describes it as an octal three-state bidirectional bus transceiver. It is intended for systems that need controlled transmit, receive, or disconnected states across parallel bus lines.
What are the key specifications of DP8308N that engineers should know?
The confirmed DP8308N specifications are 8-bit data width, non-inverting operation, bidirectional signal paths, TRI-STATE control, one transceiver element, and a 20-PDIP through-hole package. The retrieved Partstack comparison also identifies commercial temperature grade. Supply voltage, propagation delay, current ratings, enable thresholds, and operating-temperature limits are not present in the supplied verified data, so they should be confirmed in the manufacturer datasheet before design release.
Where can I download the DP8308N datasheet?
The verified National Semiconductor DP8308N datasheet index is available at https://www.alldatasheet.com/datasheet-pdf/pdf/100434/NSC/DP8308N.html. The search result identifies the document as a six-page National Semiconductor datasheet, but no document revision number was provided. Use the indexed PDF and confirm the complete pinout, electrical limits, enable logic, and timing values before substituting or modernizing the circuit.
Where can I buy DP8308N online?
DP8308N can be sourced through the verified DigiKey listing at https://www.digikey.com/en/products/detail/rochester-electronics-llc/DP8308N/11525503, which identifies the part as a 20-PDIP National Semiconductor transceiver. The supplied data does not provide a numeric unit price, distributor stock quantity, or guaranteed lead time. Current price and inventory should therefore be confirmed directly with the seller before placing an order.
What is the price of DP8308N?
The verified data does not state a numeric price for DP8308N, so the unit price is listed as 0.00 only as an unavailable-data placeholder and must not be treated as a quotation. The DigiKey result confirms a product listing and invites checking pricing and availability, but no price tier was captured. Request a current quote from DigiKey or another authorized distributor as of 2026-10-22.
What is the lead time for DP8308N?
The supplied sources do not state a numeric lead time for DP8308N. DigiKey describes the listing as available for buying and shipping, but that wording does not provide a guaranteed lead time or stock quantity. Because this is a legacy 20-PDIP interface IC, procurement planning should include a distributor confirmation and, where necessary, an alternate-source review before committing to a production schedule.
Is DP8308N in stock?
The verified DigiKey result says “Buy now, ships today,” but it does not provide a current numeric stock count. Treat the part as potentially available rather than guaranteed in stock, and confirm inventory at order entry. ZDI also identifies DP8308N as a sourceable component and requests a quote, which indicates that availability may depend on current sourcing rather than a fixed stocked quantity.
What is the difference between DP8308N and DP8308?
The verified results describe both DP8308N and DP8308 as 8-bit TRI-STATE bidirectional bus transceivers. The supplied data does not provide enough verified electrical timing, enable, voltage, or pin-level details to quantify their differences. The DP8308N listing specifically identifies the N variant in a 20-PDIP package, while the separate DP8308 result confirms the family function but not a complete parameter comparison. Consult both datasheets before treating either part as interchangeable.
DP8308N vs DP8212N - which is better for a legacy parallel bus?
The supplied comparison search identifies DP8212N as a comparable part to DP8308N, but it does not provide verified package, timing, voltage, or control-polarity data. Therefore, neither part can be selected responsibly as the better replacement from the supplied evidence alone. Compare the exact pinout, data direction, three-state enable logic, supply voltage, propagation delay, and load-current ratings before deciding.
When should I choose DP8308N over another bus transceiver?
Choose DP8308N when the design specifically requires a non-inverting 8-bit TRI-STATE bidirectional interface in a 20-PDIP footprint and the manufacturer’s electrical limits match the bus. It is particularly relevant to legacy through-hole systems rather than compact surface-mount designs. Do not select it merely by function alone: verify voltage levels, timing, drive capability, enable polarity, temperature grade, and lifecycle availability.
Is DP8308N suitable for industrial control equipment?
DP8308N may be suitable for a legacy industrial control board if its verified operating limits and commercial temperature grade satisfy the system requirements. The supplied comparison data identifies a commercial temperature grade, but it does not provide the numeric operating-temperature range, supply voltage, or timing limits. Validate those specifications in the manufacturer datasheet and account for industrial noise, grounding, protection, and connector requirements.
Can DP8308N replace DP8308?
The available sources confirm that DP8308N is an 8-bit non-inverting TRI-STATE bidirectional transceiver in a 20-PDIP package, but they do not provide a verified pin-to-pin comparison between DP8308N and DP8308. A replacement decision requires confirmation that supply voltage, pinout, enable polarity, timing, and output loading are identical. Treat DP8308 as a potential family relative, not a confirmed drop-in substitute.
What is the best drop-in replacement for DP8308N?
No verified drop-in replacement can be named from the supplied cross-reference results. The searches returned generic cross-reference tools and comparison pages, but no candidate was confirmed as having the same 20-PDIP pinout and matching electrical behavior. Because strict drop-in qualification requires verified package, pin compatibility, and parameter proximity, DP8308N should be replaced only after manufacturer documentation or a qualified engineering cross-reference confirms all three.
What is the pinout of DP8308N?
The verified search confirms a 20-PDIP package but does not provide the individual pin names or numbering. Consequently, a complete pinout array cannot be populated without guessing. Use the linked National Semiconductor datasheet PDF for pin assignments, especially enable and direction controls, because incorrect control polarity can cause bus contention or unintended high-impedance states.
How does TRI-STATE operation help DP8308N bus designs?
TRI-STATE operation allows each transceiver output to be actively driven or placed in a high-impedance state, which is useful when multiple devices share a parallel bus. The DP8308N’s bidirectional architecture can support transmit and receive paths while disabled outputs avoid unnecessary contention. The control signals must still be sequenced correctly, and exact enable timing and polarity must be verified from the manufacturer datasheet.

선택 가이드

Select DP8308N for a legacy parallel-bus design that specifically needs an 8-bit, non-inverting, bidirectional TRI-STATE transceiver in a 20-PDIP package. It is a practical candidate for repair, retrofit, and industrial or educational through-hole boards, provided the original system uses compatible logic levels and timing. Consider DP8308 or DP8308N/A+ only after confirming their pinout, voltage, enable, and timing data. DP8212N, DP8212MJ, AM8304BX, and CX8286 are comparison leads, not confirmed drop-in replacements, because the supplied sources do not establish matching packages or electrical specifications. For modern compact products, prefer a currently active surface-mount transceiver unless legacy compatibility makes the DIP package essential.

설계 노트

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.
