DS90C402M

Overview

The DS90C402M/NOPB is a dual LVDS receiver manufactured by Texas Instruments, designed for high-speed data transmission. 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 a maximum data rate of 155.5 Mb/s and features an input type of LVDS with TTL output compatibility. Key electrical parameters include a propagation delay of 6 ns and a power dissipation of 1.025 W. The component functions within a temperature range of -40°C to +85°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Dual channel architecture providing two independent low-voltage differential signaling receivers
• LVDS to TTL translation capability for interfacing with standard digital logic
• High-speed data transfer support up to 155.5 Mb/s
• Robust operation across extended industrial temperature ranges

Applications

• Video signal processing and display interfaces
• High-speed data acquisition systems
• Industrial communication networks requiring noise immunity
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (e.g., NOPB) against the required datasheet revision to ensure compliance with RoHS standards and lead-free manufacturing processes. Confirm that the SOIC-8 package dimensions match the target PCB footprint. Cross-reference the manufacturer part number with official Texas Instruments documentation to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when a dual LVDS receiver interface is required for TTL-compatible downstream logic. Ensure the system design accommodates the 5 V supply voltage constraint and the 155.5 Mb/s bandwidth limit. Consider the SOIC-8 package size for space-constrained layouts. Verify thermal management requirements given the specified power dissipation characteristics under maximum load conditions.

Part Context

This component belongs to the DS90C40x series of LVDS interface devices from Texas Instruments. It serves as the receiver counterpart to drivers like the DS90C401MX. The series is engineered for reliable differential signaling in noisy environments, maintaining signal integrity over longer cable runs compared to single-ended alternatives.

Replacement Considerations

The DS90C401MX/NOPB is a related device but functions as a driver rather than a receiver. Direct substitution requires verifying if the application needs signal reception or transmission. No other direct pin-to-pin receiver equivalents are confirmed in the provided source material.
