DS90LV027AHM

Overview

The DS90LV027AHM is a high-speed LVDS dual differential driver manufactured by Texas Instruments. It supports data rates up to 600 Mb/s with CMOS or TTL input compatibility. The device operates on a single 3 V to 3.6 V power supply, typically 3.3 V, and functions within an extended temperature range of -40°C to +125°C. Packaged in an 8-pin SOIC (D) surface-mount format, it features low propagation delay of 2 ns and minimal power dissipation of 1.19 W. This component is designed for applications requiring reliable high-speed serial data transmission with low electromagnetic interference.

Feature Summary

• Supports high-speed differential signaling compliant with TIA/EIA-644 standards
• Operates with standard CMOS or TTL logic inputs for easy integration
• Provides low skew and low propagation delay for precise timing
• Includes power-down protection placing outputs in a high-impedance state

Applications

• High-speed serial data links in industrial equipment
• Point-to-point communication in display interfaces
• Data acquisition systems requiring low noise transmission
• Automotive electronics operating in harsh thermal environments

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature rating. Ensure the ordering part number matches the required automotive or industrial grade specifications. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance and current production status before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel LVDS driver is needed for high-speed data transmission over short distances. It is suitable for designs requiring compatibility with standard logic levels and operation in high-temperature environments. Consider the SOIC-8 package constraints and ensure adequate PCB space for the required trace impedance matching and termination resistors.

Part Context
