Product details
Overview
SN65LVDS1DBVR from Texas Instruments is a single-channel LVDS line driver IC designed for high-speed point-to-point data transmission. It accepts LVTTL input signals, delivers differential LVDS outputs compliant with ANSI TIA/EIA-644, operates from 2.4V–3.6V supply, provides 350mV typical differential output into 100Ω, and supports signaling rates up to 630Mbps - widely deployed in wireless infrastructure baseband interconnects.
For engineers reviewing the SN65LVDS1DBVR datasheet, SN65LVDS1DBVR pinout, SN65LVDS1DBVR application, or SN65LVDS1DBVR equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated SOT-23-5 package mapping, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The SN65LVDS1DBVR implements a current-mode differential driver architecture with internal common-mode regulation, maintaining 1.2V ±75mV VOC across 2.4V–3.6V VCC. Its LVTTL input stage includes 5V tolerance via integrated Zener clamping and internal pulldown, enabling direct interface with legacy 5V logic without level shifters.
Propagation delay is tightly controlled at 1.7ns (typ), with pulse skew ≤0.3ns and rise/fall times ≤1ns under 10pF load. Output high-impedance state is enforced when VCC drops below 1.5V, supporting hot-swap and power sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.4V–3.6V - enables operation across industrial and battery-powered systems with wide rail tolerance |
| Differential Output Voltage (VOD) | 247–454mV into 100Ω - meets TIA/EIA-644 minimum while ensuring low EMI and signal integrity on PCB traces |
| Max Signaling Rate | 630Mbps - supports high-throughput serial links in baseband and timing-critical backplane applications |
| Propagation Delay | 1.5–3.1ns (tPLH/tPHL) - enables sub-nanosecond timing alignment in synchronous clock distribution |
| Input Voltage Tolerance | 5V-tolerant LVTTL input - eliminates need for external level translators when interfacing with 5V microcontrollers or FPGAs |
| ESD Rating (Bus Pins) | ±9kV HBM - ensures robustness against handling and system-level ESD events in telecom equipment |
| Operating Temperature | –40°C to +85°C - qualified for deployment in outdoor wireless infrastructure and industrial control cabinets |
Pinout & Package
SOT-23-5 package (2.90 mm × 1.60 mm), surface-mount, lead-free, RoHS-compliant. Thermal resistance RθJA = 322.6°C/W; max power dissipation at TA ≤ 25°C is 385 mW.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power supply input | Single 2.4–3.6V rail; powers internal biasing, output drivers, and input protection circuitry |
| 2 - GND | Ground reference | Return path for all internal currents; must be low-inductance connection to minimize noise coupling |
| 3 - Z | Differential inverting output | LVDS-compliant complementary output; paired with Y to form 100Ω differential transmission line |
| 4 - Y | Differential non-inverting output | LVDS-compliant primary output; requires matched trace length and impedance to Z for skew control |
| 5 - D | LVTTL digital input | 5V-tolerant single-ended logic input; internal pulldown ensures defined low state if left floating |
Key Features
| Feature | Design Value |
|---|---|
| LVDS standard compliance | Fully meets ANSI TIA/EIA-644 - guarantees interoperability with industry-standard receivers like SN65LVDT2 |
| Integrated power-on reset | Forces Y/Z outputs to high-impedance when VCC < 1.5V - prevents bus contention during power-up/down sequencing |
| Low EMI emission profile | 350mV differential swing + controlled slew rate - reduces radiated emissions by >10dB vs higher-swing interfaces |
| Thermal performance optimization | NC pins (3,4,5 in DBV top view) are die-isolated - grounding them improves heat dissipation in compact layouts |
| Robust input protection | 7V Zener diodes on D input - withstands transient overvoltage without latch-up or parametric shift |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS1D | SOIC-8 package (4.90 mm × 3.91 mm); identical electrical specs; includes NC pins at positions 3,5,6 | Preferred for manual assembly, prototyping, or thermal designs requiring larger pad area and lower RθJA (172.4°C/W) | Select when board space permits larger footprint and thermal management is prioritized over miniaturization. |
| MAX3041ESA+ | 5V supply only; 250mV min VOD; 250Mbps max rate; ±15kV ESD; no 5V-tolerant input | Used in industrial RS-422/485 hybrid systems where higher ESD immunity outweighs speed loss | Choose only if 5V-only supply and extreme ESD robustness (>±15kV) are mandatory and 630Mbps is not required. |
Compared with SN65LVDS1D, the SN65LVDS1DBVR offers 40% smaller footprint and higher thermal resistance but identical signaling performance; compared with MAX3041ESA+, it delivers 2.5× higher data rate and 5V-tolerant input at the cost of lower ESD rating - making SN65LVDS1DBVR optimal for space-constrained, high-speed, mixed-voltage embedded designs.

FAQ
What is the maximum signaling rate supported by the SN65LVDS1DBVR?
The SN65LVDS1DBVR supports signaling rates up to 630Mbps, as specified in the official Texas Instruments datasheet SLLS373M. This maximum rate is achievable under recommended operating conditions (VCC = 2.4V–3.6V, TA = –40°C to +85°C, RL = 100Ω) and assumes proper PCB layout with controlled impedance and minimal stub length. The SN65LVDS1DBVR maintains TIA/EIA-644 compliance across this full range.
Does the SN65LVDS1DBVR require external termination resistors?
No, the SN65LVDS1DBVR is a driver-only device and does not include internal termination. It must drive a properly terminated 100Ω differential transmission line - either via external 100Ω resistor at the receiver end or integrated termination in a companion receiver such as SN65LVDT2. The SN65LVDS1DBVR itself has no internal termination and expects the load to be externally provided.
Can the SN65LVDS1DBVR interface directly with 5V logic devices?
Yes, the D input of the SN65LVDS1DBVR is explicitly 5V-tolerant per the datasheet, allowing direct connection to 5V LVTTL or CMOS outputs without level-shifting circuitry. This is implemented via internal Zener clamping and is validated across the full operating temperature range. Input thresholds remain at VIH = 2.0V and VIL = 0.8V regardless of applied input voltage up to 5V.
What happens to the outputs of the SN65LVDS1DBVR when VCC falls below 1.5V?
When VCC drops below 1.5V, the SN65LVDS1DBVR activates its internal power-on reset circuitry, forcing both Y and Z outputs into a high-impedance state. This behavior prevents bus contention during power sequencing, brown-out conditions, or hot-swap events. The high-Z state is maintained until VCC rises above the 1.5V threshold and stabilizes.
Is the SN65LVDS1DBVR pin-compatible with other devices in the SN65LVDxx family?
No, the SN65LVDS1DBVR is not pin-compatible with SN65LVDS2DBV or SN65LVDT2DBV. While all three share the SOT-23-5 package, their pin functions differ: SN65LVDS1DBVR uses pins 3(Z),4(Y),5(D); SN65LVDS2DBV uses pins 3(A),4(B),5(R); and SN65LVDT2DBV shares the same pinout as SN65LVDS2DBV but adds internal 110Ω termination. Swapping them without redesign will result in incorrect signal routing or failure.
