Product details
Overview
DS90LV027ATMX/NOPB from Texas Instruments is a dual LVDS differential driver IC designed for high-speed point-to-point data transmission. It delivers 360-mV differential output swing at 3.3-V supply, supports up to 350 MHz operation (700 Mbps), and features 0.7-ns max differential skew and 1.5-ns max propagation delay. It serves as an LVCMOS-to-LVDS translator in industrial automation and multi-function printer interfaces.
For engineers reviewing the DS90LV027ATMX/NOPB datasheet, DS90LV027ATMX/NOPB pinout, DS90LV027ATMX/NOPB application, or DS90LV027ATMX/NOPB equivalent, key selection criteria include differential skew tolerance, 3.3-V single-supply compatibility, SOIC-8 flow-through layout, and interoperability with TIA/EIA-644-compliant receivers such as DS90LV028A.
Technical Context
The DS90LV027ATMX/NOPB implements a current-mode LVDS driver architecture with two independent channels, each sourcing ±3.1 mA nominal loop current into a 100-Ω termination. Its balanced current-source design ensures flat power dissipation versus frequency-46 mW static, scalable with switching activity-and eliminates rail-to-rail overlap current typical of voltage-mode drivers.
It operates across −40°C to +85°C with 3.0–3.6 V supply, provides power-off protection (outputs enter high-impedance state when VCC = 0 V), and maintains <0.4 ns channel-to-channel skew. The device requires external 100-Ω differential termination and is incompatible with AC-coupled or unterminated configurations.
Key Specifications

Pinout & Package
DS90LV027ATMX/NOPB is housed in an 8-pin SOIC (D package), 4.90 mm × 3.91 mm body size, with gull-wing leads and RoHS-compliant matte tin (SN) finish. The flow-through pinout minimizes trace crossing and enables matched-length routing of differential pairs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power supply input | 3.3-V primary supply; requires local 0.1-μF ceramic decoupling adjacent to pin. |
| DI 1 (Pin 2) | Input 1 | TTL/CMOS-compatible single-ended data input driving Channel 1. |
| DI 2 (Pin 3) | Input 2 | TTL/CMOS-compatible single-ended data input driving Channel 2. |
| GND (Pin 4) | Ground reference | Common return path for supply and signal currents; must connect to low-impedance ground plane. |
| DO− 2 (Pin 5) | Output 2, inverting | LVDS complementary output for Channel 2; routed with DO+ 2 as controlled-impedance differential pair. |
| DO+ 2 (Pin 6) | Output 2, non-inverting | LVDS true output for Channel 2; forms 100-Ω terminated differential pair with DO− 2. |
| DO+ 1 (Pin 7) | Output 1, non-inverting | LVDS true output for Channel 1; forms 100-Ω terminated differential pair with DO− 1. |
| DO− 1 (Pin 8) | Output 1, inverting | LVDS complementary output for Channel 1; routed with DO+ 1 as controlled-impedance differential pair. |
Key Features
| Feature | Design Value |
|---|---|
| Current-mode LVDS architecture | Delivers stable 3.1-mA loop current independent of frequency-enables predictable power scaling and low EMI. |
| Flow-through pinout | Separates inputs (Pins 2–3) and outputs (Pins 5–8) on opposite sides-simplifies layer stacking and differential trace length matching. |
| Power-off protection | Outputs automatically enter high-impedance state when VCC = 0 V-prevents back-driving or bus contention during hot-swap or power sequencing. |
| TIA/EIA-644 compliance | Fully conforms to LVDS electrical standards-guarantees interoperability with industry-standard receivers including DS90LV028A, SN65LVDS1, and MAX9100. |
| Industrial temperature range | Rated for −40°C to +85°C operation-validated for deployment in building automation controllers and outdoor grid monitoring equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS1DR | Single-channel, 3.3-V LVDS driver; 400 Mbps max; SOIC-8 package; no power-off high-Z mode. | Suitable only for single-link applications; lacks dual-channel integration and fail-safe power-down behavior. | Select when board space permits discrete channel implementation and power sequencing excludes hot-swap scenarios. |
| MAX9100ESA+ | Single-channel, 5-V tolerant LVDS driver; 600 Mbps max; SOIC-8; higher ICC (25 mA typ.) and larger 500-mV swing. | Requires level translation for 3.3-V systems; higher power and EMI limit use in thermally constrained designs. | Choose only if legacy 5-V supply rails exist and system-level noise immunity justifies increased power and swing. |
Compared with SN65LVDS1DR and MAX9100ESA+, DS90LV027ATMX/NOPB uniquely combines dual-channel integration, 3.3-V native operation, power-off high-Z, and sub-nanosecond skew-making it optimal for compact, thermally sensitive, and hot-pluggable industrial interfaces where channel pairing and supply simplicity are critical.

FAQ
What is the maximum operating frequency supported by DS90LV027ATMX/NOPB?
The DS90LV027ATMX/NOPB supports a maximum operating frequency of 350 MHz, corresponding to a data rate of 700 Mbps under specified conditions (RL = 100 Ω, CL = 15 pF). This value is validated per the switching characteristics table in the official datasheet and reflects guaranteed performance across the full industrial temperature range.
Does DS90LV027ATMX/NOPB require external termination resistors?
Yes, DS90LV027ATMX/NOPB requires a 100-Ω differential termination resistor placed at the receiver end of the transmission line. As a current-mode LVDS driver, it relies on this resistive load to convert output current into a detectable differential voltage (VOD); operation without termination violates TIA/EIA-644 compliance and risks signal integrity failure.
Can DS90LV027ATMX/NOPB interface directly with 5-V logic inputs?
No, DS90LV027ATMX/NOPB accepts TTL/CMOS inputs referenced to its 3.3-V supply (VIH = 2 V min., VIL = 0.8 V max.) and is not 5-V tolerant. Direct connection to 5-V logic sources may exceed absolute maximum input voltage ratings (−0.3 V to 3.6 V) and cause permanent damage. Level-shifting circuitry is required for 5-V system interfacing.
What happens to DS90LV027ATMX/NOPB outputs when VCC is removed?
When VCC is removed or driven to 0 V, DS90LV027ATMX/NOPB outputs enter a high-impedance state due to built-in power-off protection. This prevents back-driving of the LVDS bus and eliminates contention in hot-swap or partial-power-down scenarios-ensuring safe operation in modular industrial systems.
Is DS90LV027ATMX/NOPB compatible with the DS90LV028A receiver?
Yes, DS90LV027ATMX/NOPB is explicitly designed to pair with the DS90LV028A dual LVDS receiver. Both devices share matched electrical specifications-including 360-mV differential swing, 100-Ω termination requirement, and TIA/EIA-644 compliance-enabling seamless point-to-point link implementation with minimal design validation effort.
