DS90LV019TM

Overview

The DS90LV019TM is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments, originally part of the National Semiconductor portfolio. It integrates two independent LVDS drivers and two receivers within a single package. The device supports data rates up to 100 Mb/s and operates on a single 3.3V or 5.0V power supply. Key electrical parameters include a maximum supply voltage of 3.6V for 3.3V systems, an operating temperature range from -40°C to +85°C, and a propagation delay of 7 ns. It accepts LVCMOS, LVTTL, or LVDS inputs and provides TTL, LVTTL, or LVDS outputs. The component is housed in a 14-pin SOIC surface-mount package.

Feature Summary

• Supports dual-channel bidirectional communication with independent driver and receiver sections.
• Compatible with standard logic families including LVCMOS, LVTTL, and LVDS input/output types.
• Designed for high-speed point-to-point interconnects with low electromagnetic interference.
• Features a pinout compatible with legacy devices to simplify PCB layout transitions.

Applications

• High-speed serial data transmission in industrial control systems
• Video signal distribution and display interfaces
• Data acquisition systems requiring isolated signal paths
• Telecommunications equipment front-end interfaces

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor's semiconductor business. Ensure the ordering suffix matches the required packaging format, such as tape-and-reel or cut-tape options. Confirm RoHS compliance status through the specific datasheet revision, as environmental declarations can vary by production batch and region. Cross-reference the full part number with official distributor catalogs to ensure availability and authenticity.

Selection Notes

Select this component when a design requires two independent LVDS channels in a compact form factor. It is suitable for applications needing conversion between parallel logic levels and differential signals. Consider the 14-pin SOIC package constraints for trace routing. Verify that the system power supply aligns with either the 3.3V or 5.0V operational modes specified in the electrical characteristics table.

Part Context

This device belongs to the DS90LV01x family of LVDS interface controllers. It serves as a bridge between parallel digital buses and high-speed differential transmission lines. The TM suffix indicates a specific thermal and mechanical variant within the broader product line. It complements other members like the DS90LV011 and DS90LV017 by offering multi-channel capability in a standardized footprint.

Replacement Considerations

The DS90LV019TMX/NOPB is a direct equivalent with identical functionality and specifications. Check for updated suffixes indicating revised packaging or environmental compliance. No functional substitutes are publicly confirmed; verify pin compatibility if considering alternative manufacturers' LVDS transceivers.
