Product details
Overview
SN65HVD3083EDGSR from Texas Instruments is a full-duplex RS-485 transceiver IC designed for industrial bus communication. It operates at 1 Mbps signaling rate, draws 375 μA typical supply current in enabled mode, features 16 kV bus-pin ESD protection, and supports up to 256 nodes per bus using 1/8 unit-load input impedance. It is used in motion controllers and battery-powered industrial networks.
For engineers reviewing the SN65HVD3083EDGSR datasheet, SN65HVD3083EDGSR pinout, SN65HVD3083EDGSR application, or SN65HVD3083EDGSR equivalent, key selection criteria include its 1 Mbps data rate, MSOP-10 package, failsafe receiver behavior, shutdown current of 2 nA, and TIA/EIA-485A compliance for robust noise-immune differential communication.
Technical Context
This device integrates a balanced driver and receiver in a single monolithic IC for full-duplex RS-485/RS-422 operation. Its driver delivers ≥1.5 V differential output voltage into 54 Ω, while the receiver provides ±0.01 V differential threshold with 30 mV hysteresis and failsafe operation on open/short/idle bus conditions.
The IC uses independent enable controls (DE for driver, RE for receiver), supports hot-plug operation via power-up glitch-free design and internal POR, and maintains high-impedance outputs during shutdown - enabling clean bus arbitration and low-power system sleep modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signaling Rate | 1 Mbps - supports medium-speed industrial control links without overspecifying timing margins. |
| Supply Current (Enabled) | 375 μA typical - enables multi-node battery-powered systems with extended runtime. |
| Supply Current (Shutdown) | 2 nA typical - allows deep-sleep states in energy-constrained edge devices. |
| Differential Output Voltage | ≥1.5 V into 54 Ω - ensures reliable logic-level detection across long cables and noisy environments. |
| Bus Pin ESD Protection | 16 kV HBM on A/B/Y/Z - protects against field-induced transients in factory-floor installations. |
| Input Load | 1/8 unit-load - permits up to 256 transceivers on a single RS-485 bus segment. |
| Operating Temperature | –40°C to +85°C - qualified for use in uncontrolled industrial enclosures and outdoor automation cabinets. |
Pinout & Package
SN65HVD3083EDGSR is housed in a 10-pin VSSOP (DGS) package, measuring 3.0 mm × 3.0 mm × 1.0 mm, with exposed thermal pad and gull-wing leads compatible with standard surface-mount reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D) | Driver Input | Logic-level data input controlling Y/Z differential driver outputs. |
| 2 (RE) | Receiver Enable | Active-low control: drives R output when low; places R in high-Z when high or open. |
| 3 (DE) | Driver Enable | Active-high control: enables Y/Z outputs when high; disables to high-Z when low or open. |
| 4 (GND) | Ground Reference | Primary signal return path for internal circuitry and bus common-mode reference. |
| 5 (VCC) | Power Supply | 5-V nominal supply (4.5–5.5 V range); powers all internal analog and digital blocks. |
| 6 (A) | Bus Non-Inverting Input/Output | RS-485 bus terminal; connects to A-line of twisted-pair cable; receives and transmits differential signals. |
| 7 (B) | Bus Inverting Input/Output | RS-485 bus terminal; connects to B-line; complements A for differential signaling and reception. |
| 8 (Y) | Driver Output (Non-Inverting) | Differential driver output paired with Z; sourced from D input when DE = high. |
| 9 (Z) | Driver Output (Inverting) | Differential driver output paired with Y; complements Y polarity during transmission. |
| 10 (R) | Receiver Output | Single-ended logic-level output reflecting differential state of A–B; active when RE = low. |
Key Features
| Feature | Design Value |
|---|---|
| Failsafe receiver | Guarantees high R output when bus is open, shorted, or idle - prevents undefined logic states in fault conditions. |
| Hot-plug capable | Power-up/power-down glitch-free operation with internal POR ensures no spurious bus transitions during power sequencing. |
| 1/8 unit-load input impedance | Enables 256-node network scalability without bus termination or repeater requirements. |
| 16 kV HBM ESD on bus pins | Eliminates need for external TVS diodes on A/B lines in most industrial mounting configurations. |
| Independent driver/receiver enables | Allows asymmetric control - e.g., receiver always active while driver enabled only during transmit bursts. |
Applications
| Motion Controllers | Point-of-Sale Terminals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RS-485 transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVD3080EDGSR | 200 kbps max rate; lower drive strength; identical pinout and package. | Better suited for legacy low-speed sensor networks where timing margin is critical. | Select when <200 kbps suffices and ultra-low EMI emissions are prioritized over speed. |
| SN65HVD3086EDGSR | 20 Mbps max rate; faster rise/fall times; same 10-pin DGS package. | Required for high-throughput PLC backplanes or real-time motion profiling with tight jitter budgets. | Choose when >1 Mbps throughput or sub-20 ns propagation skew is mandatory. |
Compared with SN65HVD3080EDGSR and SN65HVD3086EDGSR, SN65HVD3083EDGSR delivers optimal balance of speed (1 Mbps), power efficiency (375 μA), and noise immunity - making it the preferred choice for mid-tier industrial control links where cost, size, and performance intersect.
