DS90LV028AHMX/NOPB

Overview

The DS90LV028AHMX/NOPB is a high-speed LVDS interface integrated circuit manufactured by Texas Instruments, originally part of the National Semiconductor portfolio. It features two CMOS differential drivers and receivers operating at data rates up to 400 Mb/s. The device functions on a single 3.0 V to 3.6 V power supply with a typical operating voltage of 3.3 V. It supports an extended industrial temperature range from -40°C to +125°C. Packaged in an SOIC-8 surface-mount format, it exhibits a propagation delay of 2.5 ns and handles input voltages between -100 mV and 100 mV.

Feature Summary

• Provides dual differential signaling capability for reliable high-speed data transmission over twisted-pair cables.
• Operates within an extended industrial temperature range suitable for demanding environmental conditions.
• Converts low-voltage differential signals to standard CMOS outputs for direct interfacing with digital logic.

Applications

• High-speed serial data communication links requiring noise immunity.
• Industrial control systems operating in harsh thermal environments.
• Medical equipment requiring reliable signal integrity in compact form factors.

Procurement Notes

Verify the manufacturer designation carefully, as the component is currently produced by Texas Instruments following their acquisition of National Semiconductor. Confirm that the suffix NOPB indicates lead-free and RoHS compliance. Ensure the specific AH grade matches the required extended temperature range specifications for your design environment before finalizing procurement orders.

Selection Notes

Select this component when dual-channel LVDS reception and driver functionality are required in a minimal footprint. Compare against the DS90LV028ATMX/NOPB if a lower commercial temperature range suffices. Consider the automotive-grade DS90LV028AQMAX/NOPB only if AEC-Q100 qualification is explicitly mandated by the system requirements.

Part Context

This device belongs to the DS90LV028A series of Low Voltage Differential Signaling (LVDS) components. It serves as a bridge between high-speed differential buses and standard CMOS logic interfaces. The 'H' suffix typically denotes the extended industrial temperature variant within the broader product family.

Replacement Considerations

The DS90LV028ATMX/NOPB offers identical electrical performance but operates within a commercial temperature range. For automotive applications requiring AEC-Q100 certification, the DS90LV028AQMAX/NOPB is the qualified alternative within the same package.
