DS90C401MX

Overview

The DS90C401MX is a dual low-voltage differential signaling (LVDS) driver manufactured by Texas Instruments, formerly National Semiconductor. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating voltage of 5 V. The device supports data rates up to 155.5 Mb/s and accepts CMOS or TTL input signals. It features two drivers in an SOIC-8 package, suitable for surface mount installation. The component functions reliably across an extended temperature range from -40°C to +85°C, with a propagation delay of 3.5 ns and power dissipation of 1.068 W.

Feature Summary

• Dual LVDS driver configuration for high-speed serial data transmission
• Compatibility with standard CMOS and TTL logic input levels
• Low voltage operation optimized for 5V systems

Applications

• High-speed digital signal transmission interfaces
• Display panel driving circuits
• Industrial communication links requiring noise immunity

Procurement Notes

Verify the manufacturer designation carefully, as the part was originally developed by National Semiconductor before its acquisition by Texas Instruments. Ensure the suffix matches specific packaging requirements such as tape and reel or cut tape formats. Confirm RoHS compliance status through official documentation prior to integration into production assemblies.

Selection Notes

Select this component when interfacing single-ended CMOS or TTL sources with LVDS receivers. The dual driver architecture suits applications requiring two independent high-speed channels. Consider the SOIC-8 footprint for PCB layout constraints and verify thermal management capabilities given the specified power dissipation limits under maximum load conditions.

Part Context

This component belongs to the DS90C401 series of LVDS interface integrated circuits. It serves as a bridge between conventional logic families and low-voltage differential signaling standards. The device is part of a broader family including complementary receivers like the DS90C402, facilitating complete point-to-point LVDS link implementations.

Replacement Considerations

The DS90C401M/NOPB is a verified equivalent variant within the same product line. Both parts share identical electrical specifications and pinouts. Verify that the replacement maintains the required SOIC-8 package dimensions and operational temperature range for direct substitution.
