Product details
Overview
SN65HVD10DR from Texas Instruments is a 3.3-V, half-duplex RS-485 transceiver in SOIC-8 package, delivering 32-Mbps signaling rate, ±16-kV HBM ESD protection on bus pins, and 1/2 unit-load drive capability for up to 32 nodes. It operates across –40°C to 85°C and meets ANSI TIA/EIA-485-A and ISO 8482:1993 standards, deployed in industrial process control networks requiring robust multi-drop communication.
For engineers reviewing the SN65HVD10DR datasheet, SN65HVD10DR pinout, SN65HVD10DR application, or SN65HVD10DR equivalent, this page delivers verified electrical specifications, fail-safe receiver behavior, thermal shutdown protection, driver/receiver enable timing, and real-world interface design implications - all confirmed against TI's SLLS505P production data sheet (Rev. P, Feb 2022).
Technical Context
The SN65HVD10DR integrates a 3-state differential line driver and a differential input line receiver on a single monolithic IC. Its driver supports fast edge rates optimized for 32-Mbps operation, while the receiver features open-circuit, shorted-bus, and idle-bus fail-safe functionality with ±0.065 V input threshold hysteresis.
It uses active-high driver enable (DE) and active-low receiver enable (RE), which can be externally tied together for direction control in half-duplex systems. Standby current is 1 µA typical, achieved by disabling both driver and receiver, and internal bus port isolation minimizes loading when VCC = 0 or driver is disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 3.6 V - compatible with standard 3.3-V logic rails; no level-shifting required |
| Signaling Rate | 32 Mbps - supports high-speed industrial automation links without signal integrity compromise |
| Bus ESD Protection | ±16-kV HBM on A/B pins - eliminates need for external TVS diodes in many factory-floor deployments |
| Unit Load | 1/2 - enables up to 32 transceivers on a single RS-485 bus segment |
| Fail-Safe Receiver | Open-circuit, shorted-bus, and idle-bus detection - ensures logic-high R output when bus is unterminated or faulted |
| Standby Supply Current | 1 µA typical - critical for low-power remote sensors and battery-backed field devices |
| Common-Mode Range | –7 V to +12 V - tolerates ground potential differences between nodes in large distributed systems |
Pinout & Package
SN65HVD10DR is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and 1.27-mm pitch. Thermal resistance is RθJA = 116.7°C/W (low-K board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Bus input/output | Differential bus terminal (complementary to B); connects directly to RS-485 twisted pair |
| B | Bus input/output | Differential bus terminal (complementary to A); polarity reversal defines bus logic state |
| D | Digital input | Driver data input - high/low determines A/B output polarity during transmission |
| DE | Digital input | Active-high driver enable - controls transmit mode; must be synchronized with RE for direction control |
| GND | Reference potential | Local device ground reference; separate from bus ground to support common-mode tolerance |
| R | Digital output | Receiver data output - asserted high/low based on differential voltage (VID) at A/B |
| RE | Digital input | Active-low receiver enable - disables R output when high; used with DE for half-duplex handshaking |
| VCC | Supply | 3.0–3.6-V power rail - decoupling capacitor (0.1 µF) required within 1 cm of pin per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Hot-plug glitch-free power sequencing | Enables safe insertion/removal in live backplanes without bus disruption or data corruption |
| Thermal shutdown protection | Activates at TJ ≥ 165°C to prevent latch-up or permanent damage during sustained overload |
| Bus-pin short-circuit protection | Sustains –7 V to +12 V faults on A/B without damage or supply current runaway |
| Low-current standby mode | 1 µA typical ICC allows >10-year battery life in wireless sensor node sleep cycles |
| SN75176-compatible footprint | Enables drop-in replacement in legacy 5-V RS-485 designs with minimal PCB rework |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RS-485 transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVD11DR | 10-Mbps max rate, 1/8 unit-load (256-node capacity), slower rise/fall times | Better suited for longer cables (>1 km) or lower-noise environments where speed is secondary to node count | Select when bus length exceeds 300 m or >32 nodes are required; not a drop-in replacement due to timing and load differences |
| THVD1550DR | 3.3-V supply, 50-Mbps rate, ±18-kV IEC 61000-4-2 ESD, integrated 3.3-V LDO | Supports higher-speed industrial Ethernet gateways and IO-Link masters with tighter EMC requirements | Choose for new designs needing enhanced ESD robustness or single-rail simplification; requires layout review for LDO bypassing |
Compared with SN65HVD11DR and THVD1550DR, the SN65HVD10DR uniquely balances 32-Mbps speed, 32-node scalability, and proven field reliability in harsh industrial settings - making it optimal for mid-length, high-throughput RS-485 links where cost, maturity, and thermal stability are prioritized over maximum node count or ultra-high ESD ratings.

FAQ
What is the maximum signaling rate supported by the SN65HVD10DR?
The SN65HVD10DR supports a maximum signaling rate of 32 Mbps under recommended operating conditions (RL = 54 Ω, CL = 50 pF). This is validated per TI's SLLS505P datasheet Section 7.3 and confirmed in driver switching characteristics (tPLH/tPHL ≤ 16 ns typical). Signal integrity at this rate requires controlled-impedance PCB routing and proper termination.
Does the SN65HVD10DR include fail-safe receiver functionality?
Yes, the SN65HVD10DR implements open-circuit, idle-bus, and shorted-bus fail-safe receiver behavior. When the A–B differential voltage is near zero (e.g., unterminated bus), the R output defaults to a logic-high state. This is achieved via internal biasing and is specified in TI's datasheet Section 9.4 and Figure 9-2.
Can the SN65HVD10DR operate with a 5-V supply?
No - the SN65HVD10DR is strictly a 3.3-V device with absolute maximum VCC of 6 V but recommended operating range of 3.0 V to 3.6 V. Operating outside this range risks parametric failure or reduced reliability. For 5-V systems, consider SN75HVD10 or level-shifting circuitry.
What is the unit-load rating of the SN65HVD10DR, and how many nodes can it support?
The SN65HVD10DR has a 1/2 unit-load rating, allowing up to 32 transceivers on a single RS-485 bus segment. This is defined per ANSI TIA/EIA-485-A and confirmed in TI's Device Comparison Table (Section 5). Each additional 1/2 unit-load device consumes half the bus capacitance budget of a full unit-load device like SN75176.
How does the SN65HVD10DR handle bus faults such as short circuits or overvoltage?
The SN65HVD10DR provides bus-pin short-circuit protection from –7 V to +12 V and survives transient pulses up to ±50 V (per Figure 8-12 test). Its driver limits output current to ±250 mA under fault, and thermal shutdown activates above 165°C junction temperature - protecting both the IC and the bus infrastructure.
