DS90LV019TMX/NOPB

Overview

The DS90LV019TMX/NOPB is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It integrates two LVDS drivers and two LVDS receivers within a single package, supporting data rates up to 100 Mb/s. The device operates on a supply voltage ranging from 3 V to 3.6 V, with a typical operating voltage of 3.3 V. It accepts LVCMOS, LVTTL, or LVDS input signals and provides TTL, LVTTL, or LVDS output options. Key electrical parameters include a propagation delay of 7 ns, a maximum input voltage of 2 V, and a minimum input voltage of 800 mV. The component dissipates up to 960 mW of power and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent LVDS drivers and two receivers for simultaneous signal transmission and reception.
• Flexible input compatibility allowing direct interfacing with LVCMOS, LVTTL, or LVDS logic families without external level shifting.
• Configurable output types enabling the generation of TTL, LVTTL, or LVDS signals to match downstream receiver requirements.

Applications

• High-speed serial data communication links requiring differential signaling integrity.
• Industrial control systems operating within standard industrial temperature ranges.
• Embedded systems connecting microcontrollers to peripheral devices via LVDS interfaces.

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel specifications. Ensure the ordering part number matches the required SOIC-14 or TSSOP configuration. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Validate that the supplier provides genuine Texas Instruments components to avoid counterfeit risks.

Selection Notes

Select this component when dual-channel LVDS conversion is required between single-ended logic levels and differential lines. Consider the 100 Mb/s speed limit and 3.3 V/5 V operational flexibility. Evaluate thermal dissipation capabilities given the 960 mW power rating in the chosen package. Compare against higher-speed alternatives if data rates exceed 100 Mb/s.

Part Context

This device belongs to the DS90LV019 series of LVDS interface ICs. It serves as a bridge between standard digital logic and high-speed differential transmission lines. The TMX suffix typically indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations
