DS90LT012AHMFX

Overview

The DS90LT012AHMFX is a high-temperature LVDS differential line receiver manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V, with a typical operating voltage of 3.3 V. The device supports data rates up to 400 Mb/s and features a propagation delay of 3.5 ns. It is housed in an SOT-23-5 surface-mount package. The component is rated for an extended operating temperature range from -40°C to +125°C, making it suitable for demanding industrial environments.

Feature Summary

• Supports high-speed differential signaling at data rates up to 400 Mb/s
• Operates reliably across an extended industrial temperature range up to 125°C
• Compatible with standard CMOS and TTL logic output levels

Applications

• High-temperature industrial communication systems
• Automotive electronic control units requiring robust signal integrity
• Point-to-point LVDS link receivers in harsh environments

Procurement Notes

Verify the specific suffix 'FX' against official Texas Instruments documentation to confirm availability and exact specifications, as datasheets primarily reference the 'MF' variant. Ensure compliance with RoHS directives and check for any recent product change notices regarding this specific marking code before finalizing procurement plans.

Selection Notes

Select this component when an LVDS receiver is required for applications exceeding standard commercial temperature limits. The SOT-23-5 package offers space efficiency for compact designs. Verify that the 400 Mb/s speed meets system requirements and that the 3.3 V supply aligns with the target platform's power architecture.

Part Context

This part belongs to the DS90LT012A series of low-voltage differential signaling receivers. The 'H' designation indicates high-temperature capability, while the 'FX' suffix typically denotes specific tape-and-reel packaging or marking variations compared to the standard 'MF' version. It serves as a single-channel receiver solution within Texas Instruments' interface portfolio.

Replacement Considerations

The DS90LT012ATMF/NOPB is a documented direct replacement for the discontinued DS90LT012ATMF. However, verify if the ATMF variant meets the required 125°C operating temperature, as some sources indicate an 85°C limit for the 'T' grade. Always consult the latest datasheet to ensure thermal and electrical compatibility.
