DS90LV031TM

Overview

The DS90LV031TM is a quad CMOS differential line driver manufactured by National Semiconductor, now part of Texas Instruments. It utilizes Low Voltage Differential Signaling (LVDS) technology to support data rates exceeding 400 Mbps at 200 MHz. The device accepts low-voltage LVTTL or LVCMOS input levels and converts them into low-voltage differential output signals with a typical swing of 350 mV. Powered by a single 3.3 V supply, it features a tri-state function that allows the outputs to be disabled, reducing power consumption to a typical idle state of 13 mW. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed data transmission with rates exceeding 400 Mbps using LVDS technology.
• Features a tri-state control mechanism to disable outputs and minimize power consumption during idle periods.
• Converts standard logic inputs into low-voltage differential signals for improved noise immunity.

Applications

• High-speed point-to-point interface applications requiring low power consumption.
• Replacement for higher power pseudo-ECL devices in communication systems.
• Data acquisition equipment needing fast signal switching capabilities.

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required package type and temperature grade. Confirm RoHS compliance status if environmental regulations apply to the target assembly process. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when designing interfaces that require low voltage operation and high data throughput. It serves as a direct pin-compatible alternative to older PECL-based drivers like the DS26C31. Consider the thermal management requirements for the TSSOP-16 package if operating near the upper temperature limit. Verify input voltage levels match the system's logic family standards.

Part Context

This device belongs to the DS90LV031A series of LVDS interface integrated circuits. It is designed to work in conjunction with compatible receivers such as the DS90LV032A. The series addresses the need for energy-efficient signaling in modern electronic systems where traditional ECL solutions are too power-intensive.

Replacement Considerations

The DS90LV031ATM/NOPB is a verified equivalent variant from Texas Instruments. The DS90C031 offers similar functionality but supports lower data rates up to 155.5 Mbps. Designers should verify pinout compatibility and electrical characteristics before substituting these parts.
