SN65LVDS31DG4

Drivers, Receivers, Transceivers Overview

The SN65LVDS31DG4 is a quad LVDS transmitter manufactured by Texas Instruments, designed for high-speed data transmission. It converts LVTTL/CMOS inputs to low-voltage differential signals with a maximum data rate of 400 Mb/s. The device operates on a single 3.3 V power supply and supports an industrial temperature range from -40°C to +85°C. Packaged in a 16-pin SOIC surface-mount format, it draws approximately 35 mA of quiescent current. This component facilitates reliable communication in noise-sensitive environments by utilizing differential signaling techniques.

Drivers, Receivers, Transceivers Feature Summary

• Converts parallel LVTTL or CMOS logic levels into low-voltage differential outputs for enhanced signal integrity
• Supports data transfer rates up to 400 Mb/s across four independent channels
• Operates reliably within the extended industrial temperature range of -40°C to +85°C

Drivers, Receivers, Transceivers Applications

• High-speed serial communication links requiring differential signaling
• Parallel-to-serial data conversion interfaces
• Noise-immune data transmission in industrial control systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint, as variants exist in different housing styles. Ensure the operating voltage aligns with the 3.3 V requirement specified in the official datasheet. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad driver is needed to interface LVTTL sources with LVDS receivers. It is suitable for applications requiring moderate data rates up to 400 Mb/s. Consider the 16-pin SOIC package constraints for board space. Verify that the system power supply provides a stable 3.3 V rail, as the device does not support wider voltage ranges. Evaluate thermal dissipation requirements based on the 35 mA typical current draw.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65LVDS31 family of low-voltage differential signaling transmitters. It serves as a bridge between standard logic families and high-speed differential buses. The device is engineered to minimize electromagnetic interference while maintaining signal quality over long traces. It complements receiver counterparts like the SN65LVDS32 or SN65LVDS33 in complete link designs.

Drivers, Receivers, Transceivers Replacement Considerations

The SN65LVDS31D is the non-RoHS equivalent. For pin-compatible alternatives, verify specific electrical characteristics against the SN65LVDS31PW variant.
