Overview
The DS90LV028ATM/NOPB is a dual CMOS differential line receiver within the DS90LV028A series, manufactured by Texas Instruments. It operates on a single 3V to 3.6V power supply with a typical operating current of 9 mA. The device supports data rates up to 400 Mb/s and features LVDS inputs converting to LVTTL outputs. It has a propagation delay of 2.5 ns and functions within an industrial temperature range of -40°C to +85°C. Packaged in an SOIC-8 surface-mount format, it dissipates approximately 1.025 W.
Feature Summary
- Converts low-voltage differential signaling (LVDS) inputs to logic voltage TTL (LVTTL) outputs for standard digital interfacing.
- Provides dual independent channels for simultaneous high-speed signal reception.
- Operates reliably across a wide industrial temperature range from -40°C to +85°C.
Applications
- High-speed serial communication links requiring LVDS-to-LVTTL translation.
- Industrial control systems utilizing differential signaling over twisted pairs.
- Data acquisition modules processing differential sensor inputs.
Procurement Notes
Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the suffix /NOPB confirms lead-free compliance and RoHS adherence. Confirm the package type matches the design requirements, specifically the SOIC-8 footprint. Validate that the industrial temperature grade meets the operational environment constraints.
Selection Notes
Select this component when dual-channel LVDS reception with LVTTL output is required at speeds up to 400 Mb/s. Compare against the automotive-grade DS90LV028AQMA if AEC-Q100 certification is necessary. Consider the DS90LV028AHMX variant for extended high-temperature applications up to 125°C. Ensure the PCB layout accommodates the SOIC-8 package dimensions.
Part Context
This part belongs to the DS90LV028A family of low-voltage differential receivers. It serves as a bridge between LVDS transmission lines and standard LVTTL logic circuits. The device is widely used in display interfaces and industrial data buses where noise immunity and speed are critical. It replaces older National Semiconductor designs under the Texas Instruments portfolio.
Replacement Considerations
The DS90LV028ATMX/NOPB offers the same functionality in tape-and-reel packaging instead of tubes. For automotive applications, the DS90LV028AQMAX/NOPB provides AEC-Q100 qualification. High-temperature variants include the DS90LV028AHMX/NOPB. Verify pin compatibility before substituting any alternative package or grade.
