DS90LV032ATMX

Overview

The DS90LV032ATMX is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments, following the acquisition of National Semiconductor. It functions as a quad CMOS differential line receiver designed for high-speed data transmission. The device supports data rates up to 400 Mb/s and operates on a single 3.3 V power supply with a maximum voltage of 3.6 V. It accepts LVDS input signals within a range of -100 mV to 100 mV and converts them to LVTTL outputs. Key electrical parameters include a propagation delay of 3.3 ns, an operating current of 15 mA, and a power dissipation of 1.025 W. The component is rated for industrial temperatures from -40°C to +85°C and is housed in a 16-pin SOIC package.

Feature Summary

• Provides four independent differential-to-single-ended conversion channels for LVDS applications
• Converts low-voltage differential signals to standard LVTTL logic levels
• Supports high-speed data transmission at rates up to 400 Mb/s
• Operates reliably across a wide industrial temperature range

Applications

• Industrial control systems requiring robust differential signal reception
• Automotive display interfaces utilizing LVDS standards
• Embedded systems connecting high-speed peripherals via differential lines

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Confirm whether the specific suffix indicates a tape-and-reel or cut-tape format if handling bulk quantities. Ensure the part number matches the exact pinout and electrical specifications required for the target design, as legacy components may have updated documentation versions.

Selection Notes

Select this component when a system requires converting LVDS inputs to LVTTL outputs for quad-channel processing. It is suitable for designs needing 400 Mb/s throughput with low power consumption. Consider the SOIC-16 package constraints and verify that the 3.3 V supply voltage aligns with the rest of the circuit's logic levels.

Part Context

This component belongs to the DS90LV032A series of LVDS interface ICs originally developed by National Semiconductor. Following the acquisition, Texas Instruments continued production and documentation. It serves as a specialized receiver for differential signaling applications, distinct from drivers or transceivers, focusing specifically on receiving LVDS signals and outputting compatible digital logic levels.

Replacement Considerations

Compatible substitutes include the DS90LV032ATMTC/NOPB and DS90LV032AQML variants. These parts share the same core functionality but may differ in packaging, qualification level, or specific manufacturing lot details. Verify pin compatibility and electrical characteristics before substitution.
