DS90C401MX/NOPB

Overview

The DS90C401MX/NOPB is a dual low voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It functions as a line driver with two drivers and zero receivers, converting CMOS or TTL inputs into LVDS outputs for high-speed data transmission. The device supports a maximum data rate of 155.5 Mb/s and operates within a supply voltage range of 4.5 V to 5.5 V, typically at 5 V. Key electrical parameters include a propagation delay of 3.5 ns and a power dissipation of 1.068 W. It is housed in an 8-pin SOIC package and rated for operation between -40°C and +85°C.

Feature Summary

• Dual LVDS line driver architecture for differential signal transmission
• Direct compatibility with standard CMOS and TTL logic levels
• High-speed data transfer capability up to 155.5 Mb/s

Applications

• Parallel-to-serial conversion interfaces in display systems
• High-speed data links requiring noise immunity
• Industrial control systems operating in extended temperature ranges

Procurement Notes

Verify the specific manufacturer documentation for the DS90C401MX/NOPB to confirm current production status and lead times. Ensure that the ordering suffix matches the required packaging format, such as tape and reel quantities. Cross-reference the datasheet revision history to validate pinout configurations and electrical characteristics against your design requirements before finalizing procurement.

Selection Notes

Select this component when a dual LVDS driver is required for interfacing parallel digital signals to differential transmission lines. It is suitable for applications needing 155.5 Mb/s throughput with CMOS/TTL input compatibility. Consider the SOIC-8 package constraints and 5V supply requirement. Compare against the DS90C402 if receiver functionality is also needed within the same footprint.

Part Context

This part belongs to the DS90C40x series of LVDS interface devices from Texas Instruments. These components are designed to bridge parallel bus architectures with high-speed serial differential links. The MX suffix indicates the SOIC-8 package variant. The NOPB designation confirms compliance with RoHS standards and absence of lead-based materials, aligning with modern environmental manufacturing regulations.

Replacement Considerations

The DS90C402MX/NOPB serves as a functional substitute if bidirectional communication is required, as it includes both drivers and receivers. Verify pin compatibility and ensure the additional receiver channels do not interfere with existing board layout constraints.
