DS90LV019 MDC

Overview

The DS90LV019 is a low-power CMOS differential line driver and receiver designed for high-speed point-to-point interconnects. It operates on a single 3.3V or 5.0V supply, supporting data rates up to 100 Mbps. The device integrates one differential driver and one receiver with TTL/CMOS-compatible logic interfaces. Key electrical parameters include a propagation delay of 7 ns, an operating power current of 48 mA, and a power dissipation of 960 mW (SOIC) or 790 mW (TSSOP). It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports 3.3V or 5.0V single-supply operation for flexible system integration
• Features TTL/CMOS-compatible inputs and outputs to simplify interface design
• Provides balanced output impedance for stable signal transmission
• Includes glitch-free power-on and power-off protection

Applications

• High-speed point-to-point data links
• Industrial communication systems
• Display panel interfaces

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and revision history before procurement.

Selection Notes

Select this component for applications requiring low-power LVDS signaling with simple point-to-point topology. Consider the SOIC-14 or TSSOP-14 package based on PCB space constraints. Verify that the 100 Mbps speed and 7 ns delay meet the system timing requirements. Ensure the 3.3V or 5V supply voltage aligns with the available power rails in the design.

Part Context

The DS90LV019 belongs to the DS90LV019 series of LVDS interface ICs from Texas Instruments. It serves as a fundamental building block for differential signaling solutions, offering a balance between performance and power consumption. The series supports both 3.3V and 5V operations, making it suitable for legacy and modern mixed-voltage systems.

Replacement Considerations

Potential substitutes include the FIN1019 from Fairchild Semiconductor and the MAX9164 from Maxim Integrated. These components offer similar LVDS functionality but may differ in pinout, supply voltage ranges, or package types. Verify electrical compatibility and mechanical fit before substitution.
