DS90LT012AHMFX/NOPB

Overview

The DS90LT012AHMFX/NOPB is a high-temperature, single-channel LVDS differential line receiver manufactured by Texas Instruments. It operates on a 3.3 V supply and complies with the ANSI TIA/EIA-644-A standard. The device supports switching rates exceeding 400 Mbps (200 MHz) with a typical differential skew of 100 ps and a maximum propagation delay of 3.5 ns. It features a SOT-23-5 package and is designed for applications requiring robust signal integrity in demanding thermal environments.

Feature Summary

• Complies with ANSI TIA/EIA-644-A LVDS standards for reliable data transmission
• Engineered for high-temperature operation to ensure stability in harsh conditions
• Provides low differential skew and minimal propagation delay for precise timing

Applications

• High-speed serial data communication links
• Industrial control systems operating in elevated temperatures
• Test and measurement equipment requiring precise signal reception

Procurement Notes

This component is classified as obsolete and is no longer in active production by Texas Instruments. Procurement should focus on existing stock from authorized distributors or secondary market suppliers. Verify lot dates and storage conditions carefully due to the end-of-life status. Ensure compatibility with current design requirements before finalizing orders, as long-term availability cannot be guaranteed.

Selection Notes

Select this receiver when a single-channel LVDS interface is required for high-temperature environments. It serves as a direct replacement for earlier National Semiconductor versions within the DS90LT012A family. Consider the SOT-23-5 footprint constraints and verify that the 3.3 V supply voltage aligns with the system architecture. Evaluate alternative active components if long-term supply chain stability is critical.

Part Context

Part of the DS90LV012A/DS90LT012A family of 3-V LVDS single CMOS differential receivers. The 'H' suffix denotes high-temperature capability, while 'FX' indicates the SOT-23-5 package variant. This specific part number represents an older generation product now discontinued, previously used in legacy designs requiring compact LVDS reception.

Replacement Considerations

Direct substitutes include DS90LT012ATMF/NOPB and DS90LT012AHMF/NOPB, which share similar functional characteristics but may differ in package type or temperature grade. Check datasheets for pinout compatibility and electrical parameter alignment before substitution.
