DS90LT012ATLD

Overview

The DS90LT012ATLD is a single-channel LVDS line receiver manufactured by National Semiconductor. It converts low-voltage differential signals to CMOS-compatible outputs, supporting data rates up to 400 Mbps. The device operates on a single 3.3 V supply with a maximum voltage of 3.6 V and minimum of 2.7 V. It features a propagation delay of 3.5 ns and draws approximately 9 mA of operating current. The component functions within an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Converts differential LVDS inputs to single-ended CMOS outputs
• Supports high-speed data transmission at 400 Mbps
• Operates with a single 3.3 V power supply

Applications

• LVDS to CMOS interface conversion in display systems
• Point-to-point communication links requiring signal translation
• Industrial equipment utilizing differential signaling standards

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, noting that TI acquired NSC. Confirm the specific suffix 'ATLD' corresponds to the TSSOP-8 package variant rather than other pinouts like SOT-23-5. Ensure the RoHS compliance status matches current regulatory requirements for the production batch.

Selection Notes

Select this component when interfacing LVDS sources with standard CMOS logic circuits. It serves as a direct replacement for older NSC parts in legacy designs. Verify that the required data rate does not exceed 400 Mbps and that the system voltage aligns with the 3.3 V nominal specification.

Part Context

This part belongs to the DS90LV012A family of single LVDS receivers. It shares functional similarities with the DS90LV018A but differs in package configuration. The ATLD suffix typically denotes a plastic surface-mount package, distinguishing it from die-level or tape-and-reel variants found in the same product line.

Replacement Considerations

The DS90LV012ATMF/NOPB is a documented equivalent offering identical electrical performance in a different SOT-23-5 package. Designers must verify pin compatibility during substitution due to the physical footprint difference between the TSSOP-8 and SOT-23-5 packages.
