DS90LV019TMX

Overview

The DS90LV019TMX is a low-power CMOS LVDS driver/receiver manufactured by National Semiconductor. It supports data rates up to 100 Mb/s and operates on a single 3.3V or 5.0V supply. The device integrates two drivers and two receivers in a 14-pin SOIC package. Key electrical parameters include a propagation delay of 7 ns, an operating power current of 48 mA, and a power dissipation of 960 mW. Input voltage ranges from 800 mV to 2 V, with a supply voltage range of 3.0 V to 3.6 V.

Feature Summary

• Supports high-speed differential signaling at 100 Mb/s with low electromagnetic interference.
• Compatible with TTL/CMOS logic levels for flexible interface design.
• Operates reliably across industrial temperature ranges from -40°C to +85°C.

Applications

• High-speed point-to-point interconnects
• Data communication systems requiring LVDS signaling
• Industrial control interfaces

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor's semiconductor business. Confirm that the component bears the original National Semiconductor markings or the appropriate TI transition identifiers. Ensure the suffix 'TMX' corresponds to the tape-and-reel packaging format required for automated assembly processes.

Selection Notes

Select this component when dual-channel LVDS transmission is required within a compact SOIC-14 footprint. It is suitable for designs needing compatibility with both 3.3V and 5V logic families. Consider the 7 ns propagation delay and 48 mA supply current for power budgeting and timing analysis in high-speed digital circuits.

Part Context

This part belongs to the DS90LV019 family of LVDS interface ICs. It provides balanced drive capabilities and is designed for applications demanding low jitter and minimal signal distortion. The device simplifies PCB layout through its pin-compatible architecture and robust ESD protection characteristics.

Replacement Considerations

Check for equivalents such as the FIN1019 or MAX9164 if sourcing from alternative vendors. Verify pinout compatibility and electrical specifications before substitution. Note that Texas Instruments may produce equivalent parts under updated naming conventions following the acquisition of National Semiconductor.
