DS90LV031ATM/NOPB

Overview

The DS90LV031ATM/NOPB is a quad CMOS differential line driver utilizing Low Voltage Differential Signaling (LVDS) technology. It operates on a single 3V power supply with a maximum voltage of 3.6V and accepts CMOS or TTL input levels. The device supports data rates up to 400 Mb/s with a typical propagation delay of 2 ns. It features four drivers and four receivers, housed in a TSSOP-16 package. Operating temperatures range from -40°C to +85°C, with a typical operating current of 30 mA and power dissipation of 866 mW.

Feature Summary

• Converts low voltage LVTTL or LVCMOS inputs into low voltage differential output signals for high-speed transmission.
• Supports a TRI-STATE function via EN and EN* inputs to disable outputs, reducing idle power consumption significantly.
• Designed as a replacement for higher power Pseudo-ECL devices in point-to-point interface applications.

Applications

• High-speed point-to-point interface circuits
• Industrial control systems requiring low power differential signaling
• Automotive display interfaces

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the NOPB suffix confirms lead-free and RoHS compliance. Confirm the specific package variant matches the design requirements, as packaging options may vary between reel, cut tape, and tube formats depending on the distributor source.

Selection Notes

Select this component when a quad differential driver is required for LVDS applications. Ensure the system logic levels match the CMOS/TTL input compatibility. Verify that the 3V supply voltage aligns with the target board design. Consider the thermal performance given the 866 mW power dissipation rating in the selected package.

Part Context

This part belongs to the DS90LV031A series of LVDS interface integrated circuits. Originally developed by National Semiconductor before its acquisition by Texas Instruments, it remains a standard solution for legacy and industrial designs requiring reliable differential signaling at moderate speeds.

Replacement Considerations

Direct functional substitutes include the DS90LV031ATMX/NOPB. For automotive-grade requirements, consider the DS90LV027AQMAX/NOPB if dual channels suffice. Always verify pinout compatibility and electrical specifications against the new component datasheet before implementation.
