DS90C402MX

Overview

The DS90C402MX is a dual Low Voltage Differential Signaling (LVDS) receiver manufactured by Texas Instruments, formerly National Semiconductor. It operates on a single 5 V supply with a voltage range of 4.5 V to 5.5 V. The device features two receivers capable of data rates up to 155.5 Mb/s. Input signals are LVDS compliant, while outputs provide TTL logic levels. Key electrical parameters include a propagation delay of 6 ns and a power dissipation of 1.025 W. The component functions within an operating temperature range of -40°C to +85°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Dual LVDS input channels for differential signal reception
• Conversion of low-voltage differential signals to standard TTL output levels
• High-speed data transmission capability supporting video and display interfaces

Applications

• Flat panel display systems requiring LVDS to TTL conversion
• Video graphics adapter circuits
• Digital signage and monitor interface boards

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor. Ensure the part number suffix matches the required package and environmental compliance specifications. Confirm that the specific revision aligns with current design requirements, as legacy documentation may reference National Semiconductor branding while the active component is produced by TI.

Selection Notes

Select this component when a dual-channel LVDS receiver with TTL outputs is required for 5 V logic systems. Compare against the DS90C401MX if driver functionality is needed instead of reception. Verify that the 155.5 Mb/s data rate meets the application bandwidth requirements and that the SOIC-8 footprint fits the PCB layout constraints.

Part Context

This component belongs to the DS90C40x series of LVDS interface integrated circuits. It serves as the receiving counterpart to drivers like the DS90C401MX. The series is designed for high-speed serial data transmission in display applications, facilitating reliable communication between source devices and display panels over twisted-pair cables.

Replacement Considerations

The DS90C402M/NOPB is a verified equivalent part number offering identical functionality and pinout compatibility.
