DS91M047TMAX

Overview

The DS91M047TMAX is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It functions as a quad mini-LVDS line driver and receiver pair, designed for high-speed data transmission applications. The device supports data rates up to 250 Mb/s with a typical propagation delay of 5 ns. It operates on a single 3.0 V to 3.6 V power supply, consuming approximately 75 mA of current at 3.3 V. The component accepts LVCMOS or LVTTL input signals and converts them to M-LVDS outputs. It is housed in a 16-pin SOIC package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates four independent drivers and receivers within a single package to reduce board space.
• Converts standard logic-level inputs to compliant mini-LVDS differential signals for noise immunity.
• Provides robust signal integrity over long cable runs through differential voltage swing standards.

Applications

• High-speed parallel bus interconnects in industrial automation systems
• Video display interfaces requiring reliable digital signal transmission
• Data acquisition systems connecting sensors to processing units

Procurement Notes

Verify the complete part number including suffixes such as TMAX and NOPB against official Texas Instruments documentation to ensure correct package type and lead-free compliance. Confirm that the specific revision matches the design requirements before procurement. Cross-reference manufacturer datasheets for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component when a compact solution for multiple differential channels is required without sacrificing data rate performance. Ensure the system power supply remains stable within the 3.0 V to 3.6 V range to maintain timing specifications. Consider the thermal dissipation capabilities of the SOIC-16 package if operating near maximum temperature limits or under heavy load conditions.

Part Context

This device belongs to the DS91M047 series of LVDS interface products from Texas Instruments. It is part of a broader family of signaling components designed to bridge legacy logic levels with modern differential signaling standards. The series includes variants optimized for different channel counts and speed requirements, serving as key enablers for high-bandwidth serial and parallel communication links.

Replacement Considerations

Direct substitutes include the DS91M047MA/NOPB which shares identical electrical specifications but may differ in packaging format. Verify compatibility with existing PCB footprints and signal integrity requirements when considering alternative packages within the same functional family.
