DP8340N Présentation

The Texas Instruments DP8340N is a bipolar microprocessor circuit packaged as a 24-pin dual in-line encoder transmitter, with an operating supply value of and encoder-interface parameters of . It is identified in distributor listings as “Encoder, Transmitter 24-DIP” and as a specialized integrated circuit. The package is PDIP-24, a through-hole DIP package, and the verified listings identify National Semiconductor as the manufacturer and DP8340N as the active MPN.

What is an encoder transmitter? An encoder transmitter is a dedicated interface circuit that converts mechanical or shaft-position information into electrical signals that can be interpreted by a digital system. In an incremental encoder system, the transmitter typically generates quadrature-related channel outputs, allowing a controller to determine direction, speed, and relative position. DP8340N belongs to the broader encoder-interface IC category and is intended for systems requiring a dedicated transmitter function rather than a general-purpose microprocessor or microcontroller.

The available verified data confirms the device type, package, manufacturer association, active status, and RoHS compliance. It does not provide the detailed supply-voltage rating, output characteristics, frequency limits, logic levels, pin functions, timing data, operating-temperature limits, or electrical performance needed for a complete design. Those values are therefore not inferred. The 24-DIP package provides a through-hole footprint suitable for conventional PCB assembly, prototyping, repair, and industrial or legacy equipment where surface-mount parts are not required.

Typical engineering uses include incremental position feedback in industrial automation, motor-control equipment, test systems, and legacy motion-control products. The external mechanical encoder, wiring length, supply source, input conditioning, and controller must be verified against the complete manufacturer datasheet before implementation. Because the verified information does not expose a pinout, the DP8340N pin list is marked unavailable rather than reconstructed from memory.

When integrating DP8340N, preserve the manufacturer-specified pin functions and bypass requirements, route encoder signals away from high-current switching nodes, and validate signal integrity with the intended cable and grounding scheme. The available source material identifies the part as active, but it does not provide a current manufacturer stock statement or a controlled distributor price. Procurement should therefore be treated as market-dependent and confirmed with the seller.

This page consolidates the verified distributor classification, package information, lifecycle indication, pricing reference, sourcing links, and engineering caveats for DP8340N. It intentionally separates confirmed data from missing datasheet parameters so that engineers can locate the original documentation before making a design or purchasing commitment.

Applications typiques

DP8340N convient pour 6 applications: Incremental Encoder Feedback, Industrial Position Control, Motor and Motion Systems, Test and Measurement Equipment, Legacy Automation Equipment Repair, Robotics and Positioning Platforms.

🔧

Incremental Encoder Feedback

DP8340N is classified as an encoder transmitter, making it a candidate for incremental encoder signal conditioning and position-feedback interfaces. The verified data confirms the transmitter function and 24-DIP package, but it does not provide channel timing, output levels, frequency limits, or pin assignments. Before using it, compare the encoder waveform, cable length, controller input thresholds, and every supply and signal pin against the manufacturer datasheet. A software or hardware controller must also be able to interpret the resulting channel relationships correctly.

🏭

Industrial Position Control

DP8340N can be considered for legacy industrial position-control equipment where a dedicated 24-DIP encoder transmitter is required. Its through-hole package supports conventional PCB assembly, repair, and retrofit workflows. However, the verified sources do not specify supply voltage, noise margin, propagation delay, operating temperature, or environmental qualification. Confirm those ratings and verify signal-grounding and cable-shielding practices before deploying it in a machine-control loop.

🏭

Motor and Motion Systems

The encoder-transmitter function makes DP8340N relevant to motor and motion systems that use shaft-position feedback for speed, direction, or relative-position monitoring. The verified data does not establish whether the device accepts particular encoder outputs or drives a particular controller, so the system interface must be validated electrically and mechanically. Check pinout, logic thresholds, maximum input frequency, cable termination, and controller timing. The DIP package is particularly relevant to older equipment designed around through-hole replacement parts.

🖥️

Test and Measurement Equipment

DP8340N may fit older test and measurement systems that require an encoder transmitter interface for position or motion sensing. The 24-DIP package allows straightforward insertion into existing through-hole boards, but compatibility depends on the complete electrical specification and pinout, neither of which is supplied in the verified snippets. Before retrofitting equipment, compare supply rails, signal thresholds, timing, grounding, and environmental requirements with the original circuit and its documentation.

🔧

Legacy Automation Equipment Repair

DP8340N is a plausible candidate for repairing or extending legacy automation equipment when the original documentation identifies an encoder transmitter in a 24-DIP footprint. The active listing may help locate replacement stock, but lifecycle status does not guarantee long-term supply or exact original specification. Confirm the manufacturer marking, package suffix, pinout, supply voltage, timing, and encoder frequency before soldering. Preserve the original bypassing and grounding layout where possible to avoid introducing signal-integrity problems.

🧩

Robotics and Positioning Platforms

DP8340N may be investigated for robotics and positioning platforms that use incremental encoders, particularly older or repair-oriented designs. The verified data supports only the encoder-transmitter category and package classification, so suitability cannot be inferred from the MPN alone. Validate quadrature or channel timing, logic compatibility, maximum encoder rate, cable length, supply noise, and controller input structure. A full mechanical and electrical comparison should precede any decision to use this part in a new design.

What is the DP8340N?
The DP8340N is a 24-DIP encoder transmitter integrated circuit from National Semiconductor, also presented in the verified listings as a Texas Instruments-related datasheet entry. It is a specialized interface device intended for encoder signal transmission. The available distributor classification is “Encoder, Transmitter 24-DIP,” while detailed electrical timing, logic, voltage, and frequency specifications require the manufacturer datasheet.
What package does the DP8340N use?
The DP8340N uses a 24-pin dual in-line package identified as 24-DIP or PDIP-24 in the verified distributor data. It is a through-hole package rather than a surface-mount QFN or SOIC package. The complete pin names and pin functions are marked as data needed because the supplied sources do not expose a manufacturer pinout diagram.
Is the DP8340N active?
The DP8340N is listed as active by the verified IC Online product result. Active status indicates that the part is presented as currently available in the source data, but it does not guarantee a specific quantity, price, or delivery date. Buyers should confirm current lifecycle and stock directly with an authorized supplier because distributor availability can change.
Where can I download the DP8340N datasheet?
A manufacturer-related PDF link is provided in the verified sources at https://www.worldwayelec.com/pro/texas/dp8340n/3918206/dp8340n.pdf. The supplied search data also includes a datasheet directory entry, but the available material does not provide a verified document number or page count. Treat the linked PDF as the starting point and confirm its authenticity against the original manufacturer documentation.
Where can I find the DP8340N pinout?
The supplied verified results do not include a complete pinout for DP8340N. The package is confirmed as 24-DIP, but individual pin names and functions are not provided. Do not infer the pin assignments from general encoder-circuit conventions. Download and verify the manufacturer datasheet before wiring power, encoder inputs, outputs, grounds, or control signals.
How much does the DP8340N cost?
The verified icDirectory result lists a DP8340N price of $19.00000, and that amount is used as the reference price in this page. Other distributor results advertise pricing and availability but do not provide a consistent numeric quote in the supplied snippets. Pricing is therefore market-dependent and should be confirmed as of 2026-10-22 before purchase.
Where can I buy DP8340N online?
DP8340N listings are available through the verified IC Online, ICMASS, Fullcores, Lisleapex, and YIC Electronics sources. DigiKey Marketplace also lists the part through Rochester Electronics, LLC. Because stock and authorized-channel status vary, compare the seller, condition, quantity, and return terms before ordering rather than relying on the presence of a listing alone.
What is the lead time for DP8340N?
The verified results do not state a guaranteed DP8340N lead time. One marketplace result advertises in-stock handling, while other listings direct buyers to request a quotation, so the actual lead time depends on seller inventory, quantity, package condition, and fulfillment location. Request a written lead time for the exact quantity and do not treat a marketplace listing as a firm schedule.
Is DP8340N in stock?
DP8340N availability is seller-dependent in the supplied results. Metkey lists the part as in stock with 2554 pieces, while several other sources advertise sourcing or quotation services without a confirmed quantity. The verified data does not establish one universal stock status, so check the selected distributor immediately before placing an order.
What can replace the DP8340N?
The verified cross-reference data does not identify a confirmed drop-in replacement for DP8340N. The A-Plus Industries result states that DP8340N is equivalent to SN8340, but the supplied material does not verify pin compatibility, electrical equivalence, or package-level interchangeability for that candidate. Treat SN8340 as a lead requiring datasheet confirmation, not as a confirmed drop-in alternative.
Is the DP8340N the same as SN8340?
The DP8340N is not proven to be identical to SN8340 from the supplied data alone. One cross-reference source describes DP8340N as equivalent to SN8340, but it provides no pinout, timing, voltage, or parametric comparison. Verify both manufacturer datasheets and compare every pin, supply requirement, signal level, timing parameter, and package before considering substitution.
What is the best equivalent for DP8340N?
No verified best equivalent can be identified from the supplied cross-reference results. The only named candidate is SN8340, and the available snippet does not establish pin-to-pin compatibility or matching electrical ratings. A valid replacement must use the same 24-DIP footprint, preserve every pin function, and meet the encoder timing, voltage, logic, and environmental requirements of the original design.
DP8340N versus SN8340: which is better for an encoder interface?
The supplied sources do not contain enough verified specifications to determine whether SN8340 is better than DP8340N for an encoder interface. DP8340N is confirmed as a 24-DIP encoder transmitter, while SN8340 is only described as an equivalent candidate in one sourcing result. Choose either part only after confirming identical pinout, supply voltage, output timing, logic levels, frequency capability, noise behavior, and environmental ratings.
What should I verify before replacing DP8340N?
Before replacing DP8340N, verify the complete pinout, supply-voltage tolerance, input thresholds, output levels, encoder frequency response, propagation timing, reset or enable behavior, grounding, bypass requirements, and package dimensions. The supplied data confirms only the encoder-transmitter classification and 24-DIP package, so a replacement decision based solely on the MPN or distributor equivalence claim is unsafe.
What are the key specifications of DP8340N that engineers should know?
The confirmed DP8340N specifications are its encoder-transmitter function, 24-DIP package, through-hole construction, active lifecycle listing, and RoHS compliance. Supply voltage, current, timing, logic levels, frequency limits, temperature range, and pin functions are not present in the supplied verified data and are explicitly marked as data needed. Obtain the manufacturer datasheet before final circuit design or production release.

Guide de sélection

Choose DP8340N when the target equipment specifically identifies a 24-DIP encoder transmitter and you need a source that reports the part as active and RoHS compliant. Before ordering, confirm the original manufacturer marking, complete pinout, supply voltage, encoder timing, logic levels, frequency range, and operating-temperature requirements. Consider SN8340 only as a documented cross-reference lead: it is named as equivalent in one sourcing result, but the supplied evidence does not establish pin-to-pin or parametric interchangeability. For a new design, select a replacement only after comparing the full datasheet and testing the complete encoder-to-controller signal path. For repair work, preserve the original board layout and verify the package orientation, grounding, bypassing, cable behavior, and controller thresholds. The active status of DP8340N is useful but does not guarantee long-term availability or eliminate the need for supply-chain planning.

Notes de conception

Do not rely on a distributor equivalence statement as a substitute for a complete pinout and timing comparison. The supplied cross-reference result names SN8340, but the verified data does not prove identical pin functions, voltage ratings, logic levels, or encoder frequency limits. Obtain both datasheets, map each pin, and validate signal timing before installation.

The DP8340N is verified in a 24-DIP through-hole package. Confirm the original board footprint, pin spacing, notch orientation, and any manufacturer-specific suffix before ordering. For repair or retrofit work, preserve the original component orientation and inspect the board for damaged pads, contamination, and heat stress before inserting a replacement.

Encoder signals can be affected by cable length, grounding, shielding, and nearby switching equipment. Keep encoder wiring away from high-current edges, use the grounding and shielding scheme specified by the original system, and validate thresholds and timing with the intended controller. The supplied data does not include rise time, propagation delay, or frequency limits, so these must be verified from the manufacturer datasheet.

Before applying power, verify the DP8340N supply range and required bypass components from the original documentation. Do not infer a supply voltage from the package or from a generic encoder transmitter. Check idle current, input thresholds, and output levels with the intended encoder and controller; missing power specifications make untested substitutions especially risky.
