DS92LV040ATLQA

Overview

The DS92LV040ATLQA is a four-channel low-voltage differential signaling (LVDS) transceiver manufactured by Texas Instruments, formerly National Semiconductor. It operates with LVTTL inputs and BLVDS outputs, supporting data transmission rates up to 155Mbps. The device features a 44-pin LLP package measuring 7 x 7 x 0.8mm. It functions within a supply voltage range of 3V to 3.6V and supports an operating temperature range from -40°C to +85°C. Key electrical parameters include a differential input high threshold of 0mV and a differential input low threshold of -70mV.

Feature Summary

• Four independent driver channels for parallel signal transmission
• Conversion between LVTTL logic levels and BLVDS differential signals
• Compact surface-mount packaging for space-constrained designs

Applications

• Point-to-point LVDS interconnects in industrial equipment
• Data bus interfaces requiring LVTTL to LVDS translation
• Embedded systems utilizing short-range differential signaling

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor. Ensure the specific suffix matches the required package variant and environmental rating. Confirm RoHS compliance status through official documentation before integration into production schedules.

Selection Notes

Select this component when four simultaneous LVDS channels are required with LVTTL compatibility. Verify that the 155Mbps speed meets system timing requirements. Ensure the 44-pin LLP footprint aligns with the PCB layout constraints and thermal management strategy for the target application environment.

Part Context

This device belongs to the DS92LV040 family of LVDS transceivers. It serves as a bridge between standard TTL/CMOS logic and differential signaling standards. The transition from National Semiconductor to Texas Instruments affects branding but maintains technical continuity for existing designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the TI portfolio. Verify if updated revisions offer improved electrical characteristics or packaging options while maintaining functional equivalence for the current design.
