DS90LV031ATMX/NOPB

Overview

The DS90LV031ATMX/NOPB is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It integrates four CMOS differential drivers and four receivers in a single package, supporting data rates up to 400 Mb/s. The device operates on a single 3 V power supply with a maximum voltage of 3.6 V and draws approximately 30 mA of operating current. It accepts CMOS or TTL input signals and converts them to LVDS outputs, while receiving LVDS inputs to produce LVTTL outputs. The component functions within an ambient temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP surface-mount package.

Feature Summary

• Integrates four independent differential drivers and four receivers for simultaneous bidirectional communication
• Converts between standard CMOS/TTL logic levels and low-voltage differential signaling formats
• Designed for high-speed serial data transmission with minimal electromagnetic interference

Applications

• Industrial control systems requiring robust differential signal transmission
• Automotive display interfaces connecting control units to visual displays
• Medical equipment utilizing high-reliability digital communication links

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence. Ensure the package type matches the required TSSOP-16 footprint for PCB layout compatibility. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a quad-channel solution is required to minimize board space compared to discrete drivers. Consider the 400 Mb/s speed limit against higher-speed alternatives if system requirements exceed this threshold. Evaluate the 3 V supply constraint against available power rails in the target application environment.

Part Context

This part belongs to the DS90LV031A series of LVDS interface devices. It serves as a bridge between parallel CMOS/TTL buses and serial differential lines. The device is often used in conjunction with compatible receivers like the DS90LV032A to form complete link pairs for data exchange across printed circuit boards.

Replacement Considerations

The DS90LV031ATMTCX/NOPB is a direct pin-compatible alternative offering the same TSSOP-16 package and functional specifications. Verify that any substitute maintains the 400 Mb/s data rate and 3 V operating voltage requirements.
