DS90LV027ATMX-NS

Overview

The DS90LV027ATMX is a dual high-speed differential driver manufactured by Texas Instruments, which acquired National Semiconductor. It operates on a single 3V to 3.6V supply and supports data rates up to 600 Mbps. The device accepts CMOS or TTL inputs and converts them into low-voltage differential signals (LVDS) compliant with the TIA/EIA-644 standard. Key electrical parameters include a maximum propagation delay of 1.5 ns and a typical power dissipation of 1.19 W in an SOIC-8 package. The operating temperature range spans from -40°C to +85°C.

Feature Summary

• Dual channel LVDS driver architecture for parallel signal transmission
• Direct compatibility with CMOS and TTL logic families
• Low skew performance ensuring signal integrity at high speeds
• Power-down protection feature maintaining high-impedance outputs

Applications

• High-speed serial-to-parallel data conversion interfaces
• Video display systems requiring LVDS signaling
• Industrial control networks utilizing differential communication
• Test and measurement equipment interface boards

Procurement Notes

Verify the manufacturer origin carefully as National Semiconductor was acquired by Texas Instruments. Ensure the suffix matches current TI specifications. Confirm RoHS compliance status through official datasheets. Check for obsolescence notices regarding older manufacturing lots. Validate pinout compatibility if replacing legacy components.

Selection Notes

Select this component when dual-channel LVDS driving is required within a compact SOIC-8 footprint. Compare against single-channel alternatives like the DS90LV017A if only one link is needed. Consider the DS90LV028A series if receiver functionality is also required on the same board. Verify voltage levels match the system's 3.3V logic requirements.

Part Context

This part belongs to the DS90LV027A family of LVDS interface integrated circuits. It serves as the transmitter counterpart to receivers such as the DS90LV028A. The device is widely used in applications demanding reliable high-speed data transfer over twisted-pair cables. It represents a standard solution for interfacing digital logic with LVDS transmission lines.
