MC33897D - Single-Wire CAN Transceiver | NXP Semiconductors
N.º de pieza: MC33897D ✗ Fin de vidaMC33897D Descripción general
A single-wire CAN transceiver is a CAN bus physical-layer interface that uses one communication conductor rather than the separate transmit and receive conductors used by conventional CAN implementations. The MC33897D belongs to the broader CAN transceiver and interface IC category, providing the electrical interface between a digital controller and a single-wire CAN network. Its half-duplex operating concept supports communication over a shared network medium while reducing wiring complexity compared with dual-wire CAN.
The key verified features of the MC33897D include its 1/1 driver and receiver arrangement, 12 V supply voltage, 83.33 Kbps data rate, and 14-SOIC package. The -40°C to +125°C operating range provides an extended temperature capability for demanding automotive, industrial, marine, and aircraft environments. The package is supplied in tube packaging according to the verified distributor information.
MC33897D is a legacy NXP interface component associated with the Motorola 33897 family. The manufacturer datasheet identifies the product as a single-wire CAN transceiver providing the physical layer for digital communication using CSMA/CR operation over a single-wire medium. Because the device is listed as obsolete in the verified DigiKey search result, new production availability is not expected without a qualified sourcing route. The cross-reference data identifies MC33897CTEF as a parametric equivalent candidate.
Typical uses include automotive body and module networks, agricultural machinery communications, industrial control networks, marine equipment, aircraft systems, and other installations requiring module-to-module communication over a reduced-wire-count bus. The 83.33 Kbps data rate and extended temperature range make the part relevant to legacy single-wire CAN designs, although system designers should confirm signal integrity, termination, grounding, and network topology against the manufacturer datasheet.
When designing around MC33897D, pay particular attention to the single-wire bus topology and the 12 V supply requirement. The transceiver should be placed so that its connection to the one-wire network is physically short and properly controlled, with PCB layout and external components selected according to the datasheet. Obsolete status means sourcing continuity and counterfeit avoidance are important procurement considerations.
This page combines verified manufacturer and distributor information, obsolete-lifecycle details, a documented parametric substitute, package and pinout status, and application-specific engineering guidance. It is intended to help engineers identify whether the legacy MC33897D remains electrically appropriate and how to verify a replacement before committing to a new design.

Aplicaciones típicas
MC33897D es adecuado para 6 aplicacións: Automotive Module Networks, Industrial Control Networks, Farm Equipment Communications, Marine Equipment Networking, Aircraft Module Communication, Module-to-Module Serial Links.
Automotive Module Networks
The MC33897D fits legacy automotive module-to-module networks that use a reduced-wire-count SWCAN physical layer. Its verified 83.33 Kbps data rate, 12 V supply rating, and -40°C to +125°C operating range align with vehicle electrical environments where wiring complexity and operating-temperature resilience are important. The transceiver provides the physical layer between a CAN controller and the single-wire network. Because the part is obsolete and no AEC-Q100 qualification was provided, it should be used only where an existing qualified design or controlled legacy-sourcing program justifies continued use. For new vehicle platforms, verify current qualification, protection requirements, and supply continuity with the vehicle program before selecting this device.
Recomendado
Industrial Control Networks
The MC33897D is suitable for legacy industrial control networks that communicate over one bus conductor instead of a conventional dual-wire CAN medium. Its half-duplex 83.33 Kbps interface can reduce wiring in distributed machinery, remote I/O, and controller-to-controller links, while the -40°C to +125°C range supports thermally varied industrial equipment. The single-wire bus still requires disciplined network design, including correct termination, reference grounding, controlled topology, and protection from industrial transients. Those implementation details are not quantified in the supplied verified data and should be taken directly from the NXP datasheet. For new production equipment, evaluate MC33897CTEF or a currently supported transceiver rather than building new demand around an obsolete MC33897D.
Recomendado
Farm Equipment Communications
The MC33897D can serve as the physical-layer interface in legacy farm-equipment communication networks where tractors, implements, or controllers exchange data over a single-wire CAN bus. The verified 83.33 Kbps rate is appropriate for low-to-moderate-speed control traffic, and the -40°C to +125°C specification provides a broad temperature range for outdoor agricultural machinery. A single-wire topology can reduce harness conductors, but shared-bus contention, cable length, termination, and fault behavior must be validated against the manufacturer network guidelines. The device's obsolete status is a major lifecycle concern for agricultural platforms with long service lives, so maintenance designs should favor the documented MC33897CTEF equivalent after complete pin and electrical verification.
Recomendado
Marine Equipment Networking
The MC33897D is relevant to legacy marine equipment networks that connect instruments, navigation equipment, or machinery controllers through a single communication conductor. Its -40°C to +125°C operating range covers many demanding ambient conditions, while the 83.33 Kbps half-duplex interface suits supervisory and control traffic rather than high-bandwidth streaming. Marine installations must also account for ground differences, long cable runs, connector corrosion, and transient exposure; none of those protection parameters were supplied in the verified data, so engineers must consult the full datasheet and applicable equipment requirements. Because MC33897D is obsolete, new marine designs should avoid creating another long-term dependency and consider a supported single-wire CAN transceiver.
Recomendado
Aircraft Module Communication
The MC33897D can fit legacy aircraft module-to-module communication networks that use a single-wire CAN physical layer. Its -40°C to +125°C rating and 83.33 Kbps data rate suit low-bandwidth supervisory links, and the one-wire medium can reduce conductor count in weight-conscious harnesses. Aircraft use nevertheless requires strict evidence that the selected device meets the program-specific environmental, qualification, and traceability requirements; the verified data does not identify an AEC-Q100 qualification for MC33897D. Because the part is obsolete, continued use should be restricted to already approved systems with controlled procurement. New aircraft programs should evaluate currently supported alternatives rather than treating MC33897D as a new-design standard.
Recomendado
Module-to-Module Serial Links
The MC33897D provides a physical-layer interface for digital communication between modules connected by a single-wire medium. The verified 1/1 transceiver arrangement, 12 V supply rating, and 83.33 Kbps rate make it appropriate for legacy supervisory links where reducing bus wiring is valuable. In a practical installation, the device is connected between a CAN controller and the one-wire bus, with network behavior governed by the CSMA/CR access method described in the NXP datasheet. External termination and protection must follow the manufacturer circuit because their values were not included in the supplied excerpts. For maintenance, first validate MC33897CTEF; for new modules, assess lifecycle and electrical protection requirements against currently supported interface ICs.

Notas de diseño
Do not approve a replacement based only on the word equivalent. The verified DigiKey result explicitly identifies MC33897CTEF as a parametric equivalent for MC33897D, but the supplied data does not include a complete pin comparison. Before substituting it, compare the 14-SOIC pinout, transceiver mode, logic levels, timing, supply limits, bus-idle behavior, termination network, and operating-temperature limits against both manufacturer datasheets.
Treat the single-wire CAN connection as a controlled network interface rather than a general-purpose communication line. Follow the NXP datasheet's recommended transceiver placement and external-network arrangement, minimize exposed bus-trace length where practical, keep the return or reference path short, and place required protection close to the connector. The supplied excerpts do not specify trace impedances or protection-component values, so those details must not be inferred from this page.
The MC33897D is specified for a 12 V supply, but the verified data does not provide its complete absolute-maximum or recommended operating supply range. Do not infer the permissible supply limits from the nominal 12 V description. In a replacement design, use the exact datasheet values for decoupling, bus-fault exposure, power sequencing, and shutdown behavior, and verify the 12 V rail under worst-case automotive, industrial, marine, or aircraft transients.
Obsolete status creates procurement risk in addition to technical risk. MC33897D is listed as no longer manufactured, and no current price, stock, or lead time was provided as of 2026-10-29. For maintenance builds, request traceable original stock with date code and test documentation, and consider the documented MC33897CTEF equivalent. For new designs, avoid committing to a five-part legacy family solely because the packages are similar.
Información de cumplimiento
