Product details
Overview
SN65LVDS2DBVT from Texas Instruments is a single-channel LVDS line receiver in SOT-23-5 package, converting differential LVDS inputs (≥100 mV threshold) to LVTTL-compatible outputs with 2.5 ns typical propagation delay, 2.4–3.6 V supply operation, and open-circuit fail-safe functionality. It enables high-speed point-to-point data links in telecom infrastructure and wireless baseband modules.
For engineers reviewing the SN65LVDS2DBVT datasheet, SN65LVDS2DBVT pinout, SN65LVDS2DBVT application, or SN65LVDS2DBVT equivalent, this page delivers verified electrical specs, thermal behavior at 85°C, fail-safe logic behavior under open input, and real-world substitution guidance for LVDS receiver selection in noise-sensitive, low-power embedded systems.
Technical Context
The SN65LVDS2DBVT implements a fully differential input stage with ±100 mV input voltage threshold and internal 300-kΩ pull-up resistors enabling open-circuit fail-safe output high assertion. Its LVTTL output stage delivers VOH ≥2.4 V (at VCC ≥3 V, IOH = –8 mA) and VOL ≤0.4 V (IOL = 8 mA), supporting direct interface to 3.3 V logic families without level translation.
It operates across –40°C to +85°C with supply voltage range 2.4 V to 3.6 V, exhibits 4–7 mA typical ICC under steady-state no-load conditions, and maintains input common-mode range from 0 V to VCC – 0.8 V - enabling robust interoperability with SN65LVDS1/SN65LVDS2 driver pairs despite ground shifts up to 1 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Differential input threshold | ±100 mV - ensures reliable logic decision even with low-amplitude LVDS signals and noise margin against EMI. |
| Propagation delay (tPLH/tPHL) | 1.4–3.6 ns typical - supports >400 Mbps signaling rates with sub-nanosecond timing budget allocation. |
| Supply voltage range | 2.4 V to 3.6 V - compatible with battery-backed and dual-rail industrial power domains without external regulators. |
| Fail-safe output state | High when A/B inputs open - prevents undefined logic states during cable disconnect or driver disable in telecom backplanes. |
| ESD tolerance (bus pins) | ±9 kV HBM - eliminates need for external TVS diodes on differential lines in field-deployed wireless equipment. |
| Input common-mode range | 0 V to VCC – 0.8 V - accommodates up to 1 V ground potential difference between driver and receiver PCBs. |
| Output drive strength | VOH ≥2.4 V @ –8 mA, VOL ≤0.4 V @ 8 mA - directly drives standard 3.3 V LVTTL loads without series termination or buffering. |
Pinout & Package
SOT-23-5 package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads, JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power supply input | Must be decoupled locally with ≥0.1 µF ceramic capacitor; powers internal bias and output stage. |
| GND (Pin 2) | Ground reference | Low-inductance connection required; shared return path for input common-mode and output logic swing. |
| A (Pin 3) | Differential non-inverting input | Accepts LVDS signal with 0.05–2.35 V common-mode range; paired with B for differential detection. |
| B (Pin 4) | Differential inverting input | Complements A input; differential pair rejects common-mode noise up to 2.35 V. |
| R (Pin 5) | LVTTL output | Active-high CMOS output; sinks 8 mA / sources 8 mA; compatible with 3.3 V logic families. |
Key Features
| Feature | Design Value |
|---|---|
| Open-circuit fail-safe | Forces R output high when A/B are floating - prevents system lockup during hot-plug or cable fault in telecom backplanes. |
| 5-V tolerant inputs | Not applicable - SN65LVDS2DBVT inputs are LVDS-only; only SN65LVDS1 drivers support 5-V tolerant LVTTL inputs. |
| Integrated termination | Not present - SN65LVDS2DBVT lacks internal 110 Ω termination; use external 100 Ω across A–B for impedance matching. |
| Power-on reset | Places A/B inputs and R output in high-Z state when VCC < 1.5 V - avoids glitching during brown-out or power sequencing. |
| Bus-terminal ESD | ±9 kV HBM on A/B pins - meets IEC 61000-4-2 Level 4 for unshielded board-level interfaces in industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDT2DBVT | Includes integrated 110 Ω differential termination resistor; identical pinout and supply specs. | Eliminates external 100 Ω resistor in point-to-point links; unsuitable for multidrop buses due to bus loading. | Select SN65LVDT2DBVT when simplifying layout and reducing component count is prioritized over multidrop flexibility. |
| MAX9107EUT+T | Wider supply range (2.7–5.5 V); higher ICC (10 mA typ); no open-circuit fail-safe; different pinout (SOT23-6). | Supports mixed-voltage systems but requires redesign of PCB footprint and power delivery network. | Choose MAX9107EUT+T only if 5 V compatibility or higher drive current is mandatory and layout revision is acceptable. |
Compared with SN65LVDT2DBVT, SN65LVDS2DBVT offers design flexibility for external termination placement and multidrop topologies, while MAX9107EUT+T trades fail-safe reliability and pin compatibility for broader supply adaptability - making SN65LVDS2DBVT optimal for cost-sensitive, fixed-topology telecom and industrial links where signal integrity and fault resilience are critical.

FAQ
What is the maximum signaling rate supported by the SN65LVDS2DBVT?
The SN65LVDS2DBVT supports receiver operation up to 400 Mbps, as specified in the official Texas Instruments datasheet SLLS373M. This rate is achievable under recommended operating conditions (2.4 V–3.6 V supply, –40°C to +85°C ambient), with propagation delay variation kept within 1.4–3.6 ns to maintain timing margins. The device is not rated for sustained operation above 400 Mbps.
Does the SN65LVDS2DBVT include internal termination resistors?
No, the SN65LVDS2DBVT does not include internal termination resistors. Unlike the SN65LVDT2DBVT variant, it requires an external 100 Ω differential termination resistor placed across pins A and B to match the characteristic impedance of the transmission line. This design allows flexible placement of termination and supports multidrop configurations where only the last node is terminated.
How does the open-circuit fail-safe feature work in the SN65LVDS2DBVT?
The SN65LVDS2DBVT implements open-circuit fail-safe by pulling both A and B inputs to VCC through internal 300-kΩ resistors. When the differential pair is floating (e.g., disconnected cable or disabled driver), this creates a common-mode condition that forces the output R to logic high. This behavior is confirmed in Section 8.3.2.1 of the datasheet and prevents undefined states in telecom and industrial control systems.
Can the SN65LVDS2DBVT operate with a 2.4 V supply voltage?
Yes, the SN65LVDS2DBVT is fully specified to operate at 2.4 V minimum supply voltage. Electrical characteristics including VOH (≥1.9 V at –8 mA), VOL (≤0.4 V at 8 mA), and input threshold (±100 mV) remain valid across the full 2.4 V–3.6 V range. This makes SN65LVDS2DBVT suitable for battery-powered or low-voltage industrial applications where rail headroom is constrained.
What is the thermal resistance (RθJA) of the SN65LVDS2DBVT in its SOT-23-5 package?
The SN65LVDS2DBVT in SOT-23-5 (DBV) package has a junction-to-ambient thermal resistance (RθJA) of 322.6 °C/W, as documented in Section 6.4 of the datasheet. At 85°C ambient and 7 mA typical ICC, power dissipation remains below 25 mW, resulting in negligible junction temperature rise (<8°C), eliminating need for thermal vias or heatsinking in standard PCB layouts.
