Product details
Overview
STLVDS3486BDR from STMicroelectronics is a quad-channel LVDS differential line receiver with 3.3V single-supply operation, ±100mV differential input threshold, 2.5ns typical propagation delay, and LVTTL-compatible outputs. It supports up to 400Mbps signaling rates and features open-circuit fail-safe operation for robust point-to-point or multidrop data links over 100Ω controlled-impedance media.
For engineers reviewing the STLVDS3486BDR datasheet, STLVDS3486BDR pinout, STLVDS3486BDR application, or STLVDS3486BDR equivalent, key selection criteria include differential input voltage range, channel-to-channel skew (0.3ns max), enable-controlled output disable, ESD protection (7kV on receiver pins), and TSSOP16 thermal performance across –40°C to +85°C.
Technical Context
The STLVDS3486BDR implements ANSI/TIA/EIA-644-compliant LVDS electrical characteristics, translating low-voltage differential inputs into single-ended LVTTL logic outputs. Its four independent receiver channels each feature separate enable controls (1EN/2EN on Pin 4; 3EN/4EN on Pin 12) and high-impedance output states during disable.
Input common-mode range spans 0.5|VID| to (2.4 − 0.5|VID|) V, supporting up to 1V ground potential difference between nodes. Propagation delay matching is specified via tsk(O) ≤ 0.3ns (channel-to-channel skew) and tsk(P) ≤ 0.4ns (pulse skew), enabling synchronous multi-bit data recovery in timing-critical backplane interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6V; enables direct integration with 3.3V FPGA I/O banks and avoids level-shifting circuitry. |
| Differential Input Threshold | ±100mV max; ensures reliable detection of small-swing LVDS signals under noise and jitter conditions. |
| Propagation Delay | 1.5–3.3ns; supports sub-500ps timing margins at 200MHz clock rates in parallel bus applications. |
| Channel Skew (tsk(O)) | ≤0.3ns; maintains inter-channel alignment for multi-bit data words without additional deskew logic. |
| ESD Protection | 7kV HBM on receiver pins; meets industrial handling requirements without external TVS diodes. |
| Power Dissipation | 60mW typical per receiver at 200MHz; allows dense placement in space-constrained TSSOP16 layouts. |
| Operating Temperature | –40°C to +85°C; qualified for extended industrial environments including factory automation and telecom line cards. |
Pinout & Package
TSSOP16 package: 5.0mm × 6.4mm body, 0.65mm pitch, 1.05mm max height, lead-free ECOPACK® compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 2, 6, 10, 14 (1A–4A) | Differential input non-inverting | Accepts LVDS signal pairs; referenced to corresponding B pins for differential decision. |
| 1, 7, 9, 15 (1B–4B) | Differential input inverting | Completes differential pair; VID = VA − VB determines output logic state. |
| 3, 5, 11, 13 (1Y–4Y) | Single-ended LVTTL output | Drives standard 3.3V CMOS loads; VOH ≥ 2.4V @ –8mA, VOL ≤ 0.4V @ 8mA. |
| 4 (1EN, 2EN) | Enable for Channels 1 & 2 | Active-high control; disables outputs Y1/Y2 to high-impedance when low. |
| 12 (3EN, 4EN) | Enable for Channels 3 & 4 | Independent enable for remaining two channels; supports partial bus power-down. |
| 8 (GND) | Analog/digital ground reference | Common return for supply and signal paths; requires low-inductance PCB connection. |
| 16 (VCC) | 3.3V supply input | Must be decoupled locally with ≥100nF ceramic capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Quad LVDS receiver with independent enables | Reduces component count vs discrete receivers; enables selective channel shutdown for dynamic power management. |
| Open-circuit fail-safe | Outputs default to HIGH when inputs float, preventing undefined logic states in unterminated or disconnected links. |
| Low propagation delay variation | tsk(O) ≤ 0.3ns ensures deterministic timing across all four channels for parallel data capture. |
| LVTTL-compatible outputs | Direct interface to 3.3V FPGAs, ASICs, and microcontrollers without external level translators. |
| 100mV differential input threshold | Guarantees noise immunity down to 200mVpp differential swing, compatible with legacy LVDS transmitters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVD3486DR | Identical pinout and electrical specs; TI version qualified to AEC-Q100 Grade 2 (-40°C to +105°C). | Automotive infotainment display links requiring extended temperature qualification. | Select if automotive qualification or alternate supply chain is required; otherwise functionally interchangeable. |
| MC3486DR2G | Legacy 5V-only part; incompatible supply voltage (4.75–5.25V); no 3.3V operation. | Legacy 5V systems where voltage translation is acceptable and LVDS compliance is secondary. | Only consider for brownfield 5V designs; not suitable for new 3.3V implementations. |
Compared with SN65LVD3486DR and MC3486DR2G, the STLVDS3486BDR offers optimal balance of industrial temperature range, 3.3V compatibility, and fail-safe behavior-making it preferred for new 3.3V embedded systems where supply simplicity and robustness are critical.

FAQ
Is STLVDS3486BDR pin-compatible with SN65LVD3486DR?
Yes, STLVDS3486BDR and SN65LVD3486DR share identical TSSOP16 pin assignments, electrical thresholds, propagation delays, and enable logic. Both meet ANSI/TIA/EIA-644 and deliver LVTTL outputs with ±100mV input thresholds. No PCB redesign is needed for substitution.
What is the maximum supported data rate for reliable operation?
The STLVDS3486BDR is characterized for reliable operation up to 400Mbps, verified by 2.5ns typical propagation delay and ≤0.4ns pulse skew. At this rate, signal integrity depends on proper 100Ω termination, controlled-impedance routing, and <15cm trace length on FR-4 PCBs to limit attenuation-induced jitter.
Does STLVDS3486BDR support hot-plug or live-insertion?
No, STLVDS3486BDR does not include hot-plug protection circuitry. Its absolute maximum ratings specify VCC must be applied before input signals, and VI must remain within –0.5V to (VCC + 0.5)V. Power sequencing per ST's recommended operating conditions is required to avoid latch-up or permanent damage.
Can unused channels be left unconnected without affecting performance?
Unused differential inputs (A/B pins) must be terminated to maintain common-mode voltage within 0.5|VID| to (2.4 − 0.5|VID|) V - typically via 100Ω across A–B or biasing to VCC/2. Floating inputs cause unpredictable outputs and increased supply current due to internal comparator instability.
