SN65HVD07P - High-Output RS-485 Transceiver | Texas Instruments
MPN: SN65HVD07P ✓ सक्रियSN65HVD07P अवलोकन
An RS-485 transceiver is an interface IC that combines a differential line driver and differential line receiver for robust, balanced communication over longer cables than an unbalanced single-ended interface. The SN65HVD07 family is designed to interoperate with ANSI TIA/EIA-485-A and ISO 8482E compliant devices. In the broader semiconductor hierarchy, it belongs to the interface IC class, alongside other differential bus transceivers used in industrial, building, and communications equipment.
The principal features of the SN65HVD07P include a high-output driver, controlled driver slew rate, 3-state output capability, a 1/8th unit-load option, and bus-pin ESD protection exceeding 16 kV HBM. The 1/8th unit-load capability allows up to 256 nodes on the bus when the full loading requirements of each connected device are met. Its 8-pin PDIP package also makes it practical for through-hole industrial assemblies, prototypes, and replacement work where a surface-mount footprint would require PCB changes.
The device combines a differential output driver with a differential input receiver so that transmit and receive functions share the same physical bus pins. The high-output architecture provides a differential signal greater than that required by the cited RS-485 and ISO 8482E standards. Slew-rate control helps limit unwanted reflections and electromagnetic interference on longer cables, while the failsafe receiver arrangement supports reliable interpretation of open-circuit, short-circuit, and idle-bus conditions.
Typical uses include industrial RS-485 field buses, building automation systems, remote sensor networks, instrumentation links, and factory automation equipment. The device is particularly appropriate where a board requires a through-hole transceiver, long-distance balanced signaling, multiple bus nodes, or protection against electrostatic discharge at externally accessible bus pins.
When laying out a circuit, keep the transceiver and protection components close to the cable connector, provide a low-impedance ground path, and route the balanced pair as a differential pair. Bus termination, fail-safe biasing, and any external surge protection must be designed for the intended cable length and topology. The package lead spacing is 0.300 inches, or 7.62 mm, according to the distributor listing.

सामान्य अनुप्रयोग
SN65HVD07P के लिए उपयुक्त है 6 अनुप्रयोगs: Industrial RS-485 Field Bus, Building Automation and HVAC, Remote Sensor and Telemetry Networks, Instrumentation and Test Equipment, Factory Automation Equipment, Gateways and Communications Interfaces.
Industrial RS-485 Field Bus
The SN65HVD07P fits industrial RS-485 field buses that require a balanced differential interface, multiple nodes, and a through-hole transceiver package. Its 1/8th unit-load option allows up to 256 nodes when the aggregate bus loading is acceptable, while controlled driver slew rate helps reduce unwanted reflections on installed cable. The high-output driver also targets ANSI TIA/EIA-485-A and ISO 8482E interoperability. Designers should locate the device near the bus connector, provide a ground reference, and add protection for exposed cables that may encounter surges beyond the specified 16 kV HBM ESD capability.
अनुशंसित
Building Automation and HVAC
The SN65HVD07P is appropriate for building automation controllers, HVAC equipment, and field modules that communicate over a wired RS-485 network. The differential signaling supports reliable communication across equipment spaces where ground-potential differences and common-mode noise can degrade single-ended links. Its -40°C to 85°C rating covers many indoor environmental conditions, and the 8-pin PDIP package simplifies work on controller boards assembled through holes. Designers should use controlled bus topology, provide fail-safe idle bias where necessary, and verify surge and installation requirements for field-wired terminals.
अनुशंसित
Remote Sensor and Telemetry Networks
The SN65HVD07P supports remote sensor and telemetry networks that use balanced RS-485 links to collect measurements from distributed instruments. The 1/8th unit-load option permits a larger population of low-load nodes than a standard one-eighth-unit-load comparison would allow, and the differential receiver helps reject common-mode interference coupled into field cables. Up to 256 nodes are stated when loading conditions are met. For reliable deployment, engineers should calculate the total unit load, use twisted-pair cabling, maintain a common ground path, and place any surge protection close to the connector.
अनुशंसित
Instrumentation and Test Equipment
The SN65HVD07P can serve as the balanced bus interface in laboratory and industrial instrumentation requiring a robust differential connection between a controller and remote measurement hardware. The high-output driver supports the cited RS-485 and ISO 8482E device classes, while the 1/8th unit-load characteristic is useful when several instrument nodes share a segment. Through-hole packaging is convenient for legacy laboratory equipment and prototype boards. Engineers should still treat the interface as only one part of the signal chain, validating cable impedance, termination, grounding, and instrumentation common-mode limits.
अनुशंसित
Factory Automation Equipment
The SN65HVD07P is suitable for factory automation controllers, motor-control equipment, and remote I/O modules connected through an RS-485 supervisory network. The differential interface helps maintain data integrity in electrically noisy environments, while the 3-state driver supports shared-bus implementation. Its high-output architecture and 1/8th unit-load option provide practical node density for mixed equipment networks, subject to a complete unit-load calculation. The -40°C to 85°C range suits many factory environments, but technicians should supplement the internal ESD rating with surge protection at exposed cable entries.
अनुशंसित
Gateways and Communications Interfaces
The SN65HVD07P can provide the physical RS-485 layer in a protocol gateway, data concentrator, or communications interface that translates between an embedded controller and external balanced-bus equipment. Its 8-pin PDIP package is useful when servicing or assembling older through-hole gateway boards, and the differential driver and receiver support robust cable-based links. The interface should be used only when its enable polarity, fail-safe behavior, and operating limits match the host controller. Engineers should also account for protocol timing, bus termination, ground offsets, and protection requirements when connecting the transceiver to long external cables.

डिज़ाइन नोट्स
Place the SN65HVD07P close to the RS-485 connector and route A and B as a tight, continuous differential pair over a shared ground plane. Keep the bus traces away from switching nodes and high-current return paths. Connect the transceiver ground to the connector shield or chassis reference through the grounding strategy recommended for the equipment. The verified family information identifies controlled driver slew rate, but good physical layout remains necessary to prevent reflections, common-mode conversion, and additional electromagnetic interference.
Check the supply voltage and current against the manufacturer datasheet before finalizing the board because those values were not present in the supplied verified data. Use a local, low-impedance supply connection and the decoupling arrangement specified by Texas Instruments. Do not substitute values from a similar HVD family member. If the transceiver is enabled while the bus is heavily loaded or terminated incorrectly, driver current and dissipation can rise; include a margin in the supply design and verify behavior with the final cable and termination network.
Do not treat the 16 kV HBM bus-pin ESD rating as protection against all industrial surges. For exposed RS-485 cables, add appropriately rated surge protection and confirm that its capacitance and clamping behavior do not disrupt the bus. Termination should be placed only at the physical ends of the bus, while fail-safe biasing should be designed for the complete network topology. Also verify SN65 versus SN75 enable polarity before replacing one ordering option with another.
