SN65HVD10P - 3.3V 32Mbps RS-485 | Texas Instruments
MPN: SN65HVD10P ✓ Hoạt độngSN65HVD10P Tóm tắt
An RS-485 transceiver is an interface IC that converts logic-level signals into differential voltages for a balanced communication bus and converts received differential voltages back into CMOS-compatible logic. The RS-485 interface belongs to the interface-IC hierarchy and supports robust, multipoint data links used in industrial automation, instrumentation, building controls, and communications equipment. Differential signaling improves noise immunity by comparing the voltage between two conductors rather than relying on a signal measured against ground.
The SN65HVD10P supports operation at 32 Mbps, making it suitable for data links that require substantially more signaling speed than conventional low-speed RS-485 equipment. Its three-state driver permits the bus driver to be disabled when the node is not transmitting. Available bus-pin ESD protection exceeds 16 kV using the HBM test method, according to the retrieved technical description. The family also provides a 1/8-unit-load option capable of supporting as many as 256 nodes on a bus.
The device is designed for balanced transmission lines and meets or exceeds ANSI TIA/EIA-485-A and ISO 8482:1993 requirements, as stated on the Texas Instruments family page. This makes it applicable to both industrial control networks and shorter, high-speed interconnects where point-to-point communication is suitable. Because its package is through-hole PDIP rather than a surface-mount package, the SN65HVD10P is particularly convenient for prototypes, leaded industrial assemblies, and designs that favor easy inspection or rework.
Typical uses include industrial sensor gateways, factory automation controllers, building-automation nodes, instrumentation links, and communication ports that exchange data at rates up to 32 Mbps. Half-duplex operation means the connected nodes share the bus and must avoid transmitting simultaneously. The bus direction can be controlled by a host or network controller, while receiver logic remains available for monitoring the bus according to the system architecture.
PCB implementation should preserve the differential pair as a continuous, impedance-controlled route from the transceiver to the bus connector. Place termination, biasing, protection, and any required isolation close to their associated bus nodes, and route the pair away from switching nodes and high-current paths. Because the verified source data does not provide the complete pin table or recommended external-component values, those details should be confirmed in the manufacturer datasheet before layout release.
This product page consolidates verified manufacturer specifications, distributor availability references, same-family drop-in candidates, and practical RS-485 design considerations. It also distinguishes confirmed parameters from information that still requires engineering review, helping designers evaluate the SN65HVD10P for industrial, automation, and high-speed balanced-bus applications.

Ứng dụng tiêu biểu
SN65HVD10P phù hợp cho 6 Áp dụngs: Industrial Automation Controller, Factory Sensor Gateway, Building Automation Node, Instrumentation Communication Link, Process and Environmental Monitoring, High-Speed Data Port.
Industrial Automation Controller
The SN65HVD10P fits an industrial automation node that exchanges controller or sensor data over a balanced RS-485 bus. Its 3.3 V supply operation, 32 Mbps maximum signaling rate, and -40 °C to +85 °C temperature rating provide a suitable foundation for factory equipment. The three-state differential driver supports shared-bus operation, while the 1/8-unit-load option can accommodate up to 256 nodes when loading, topology, and termination are properly designed. For implementation, place the transceiver near the bus connector and route A and B as a continuous differential pair. Confirm node timing, cable length, termination, protection, and grounding in the manufacturer datasheet and final system test.

Factory Sensor Gateway
The SN65HVD10P is appropriate for a factory sensor gateway that collects measurements from distributed field nodes. At 3.3 V and up to 32 Mbps, it supports a high-speed balanced-bus connection while limiting each node's loading through the available 1/8-unit-load option. The differential receiver and driver help preserve data integrity on balanced wiring in electrically noisy environments. The eight-pin PDIP package also simplifies through-hole prototyping and leaded industrial assemblies. During design, keep the differential route away from motor and switching-power circuits, define the bus topology before applying termination, and verify that the selected cable and node spacing support the intended signaling rate.

Building Automation Node
The SN65HVD10P can serve as the RS-485 communications interface in a building-automation controller, sensor panel, or floor-level monitoring module. It combines transmission and reception in one 3.3 V device while supporting signaling rates as high as 32 Mbps for short, high-speed links. Its -40 °C to +85 °C operating range suits many indoor industrial environments, and the three-state driver enables controlled bus participation. The transmitter and receiver should connect to a controlled bus-direction signal, and the PCB should preserve a symmetric differential pair to the connector. Terminal placement, grounding strategy, surge protection, and any isolation barrier should be reviewed for the building wiring environment.

Instrumentation Communication Link
The SN65HVD10P is a practical choice for instrumentation equipment requiring a compact, half-duplex balanced communication port. A 3.3 V supply keeps the interface compatible with modern digital control logic, while the differential driver and receiver improve noise rejection over balanced lines. The maximum 32 Mbps signaling capability is useful where the instrument must transfer burst data quickly over a relatively short instrument-bus connection. Use the receiver to monitor bus state and the three-state driver only while transmitting. Decouple the 3.3 V rail close to the device, route the pair as a controlled impedance network, and validate grounding and cable length when combining the transceiver with high-gain analog measurement circuitry.

Process and Environmental Monitoring
The SN65HVD10P suits a remote environmental-monitoring station that gathers readings from multiple distributed sensors over an RS-485 field bus. Its half-duplex architecture reduces the number of bus conductors and supports shared communication among nodes, while the available 1/8-unit-load option can reduce loading when up to 256 nodes are permitted by the system design. The 3.3 V operating supply and -40 °C to +85 °C specification support compact industrial electronics. Place termination only at the physical bus endpoints, avoid long unterminated stubs, and add surge protection where field cables leave the enclosure. Confirm the final conductor length, baud rate, grounding arrangement, and enclosure transient requirements before production.

High-Speed Data Port
The SN65HVD10P can form the physical layer of a compact high-speed data port when two devices communicate over a balanced line. Its 32 Mbps maximum signaling rate provides substantially more bandwidth than slow RS-485 links, and the integrated three-state driver and differential receiver simplify the interface to one IC. The 8-pin PDIP package is useful where through-hole assembly and manual serviceability are priorities. Because half-duplex operation requires coordinated direction control, the connected controllers must avoid simultaneous transmission. Preserve the A-to-B trace geometry, provide local supply bypassing, apply appropriate termination for the cable topology, and verify signal integrity at the intended baud rate and cable length.

Ghi chú thiết kế
Route the RS-485 A and B conductors as a continuous differential pair from the transceiver to the connector or isolation barrier. Maintain consistent pair geometry and avoid splitting the pair around unrelated circuitry. Place the transceiver and its local 3.3 V decoupling close to the interface area, while placing bus protection, termination, and bias components near the connector or at the locations dictated by the selected topology. At 32 Mbps, trace discontinuity and asymmetric routing can degrade signal integrity even when the cable itself is compliant.
Do not assume that matching nominal baud rate guarantees a usable cable length. RS-485 behavior depends on cable length, characteristic impedance, propagation delay, topology, node spacing, termination, and transceiver thresholds. Apply termination at the physical endpoints rather than at every node, avoid unnecessary stubs, and confirm biasing in an idle bus. Also ensure the controlling logic never enables two drivers on opposite ends of the same segment simultaneously because the SN65HVD10P is a half-duplex device.
Keep the differential bus away from switching-regulator loops, relay contacts, motor windings, and high di/dt conductors. Use a continuous ground reference where the interface scheme permits it, but keep the transceiver ground return independent of high-current return paths. For cables leaving an enclosure, add appropriately rated surge and ESD protection close to the connector. The IC's bus-pin ESD protection exceeding 16 kV HBM does not replace external field protection for severe industrial transients.
