SN75LVDS389DBTG4

Drivers, Receivers, Transceivers Overview

The SN75LVDS389DBTG4 is an octal low-voltage differential signaling (LVDS) driver manufactured by Texas Instruments. It integrates eight independent LVDS drivers within a single package, designed to convert LVTTL or CMOS inputs into differential LVDS outputs compliant with EIA-644 and TIA-644 standards. The device operates on a single 3.0 V to 3.6 V power supply, with a typical operating current of 70 mA. It supports data rates up to 630 Mb/s and functions reliably across a commercial temperature range of 0°C to +70°C. The component is housed in a 38-pin Thin Shrink Small Outline Package (TSSOP), facilitating surface-mount assembly for high-density circuit board designs.

Drivers, Receivers, Transceivers Feature Summary

• Integrates eight independent LVDS drivers for high-channel density applications
• Converts standard LVTTL/CMOS logic levels to differential LVDS signals
• Complies with EIA-644 and TIA-644 interface standards for signal integrity
• Operates from a single 3.3 V nominal power supply rail

Drivers, Receivers, Transceivers Applications

• Point-to-point and multi-drop digital video interfaces
• High-speed data transmission in industrial control systems
• Clock distribution networks requiring low jitter performance
• Parallel-to-differential conversion for display panels

Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to ensure lead-free compliance and RoHS certification. Confirm the DBT package variant matches the required 38-pin TSSOP footprint for PCB layout compatibility. Check the datasheet for specific moisture sensitivity level handling requirements during soldering processes to prevent package damage.

Drivers, Receivers, Transceivers Selection Notes

Select this component when eight differential channels are required from a single IC to reduce board space. Ensure the input voltage levels match the system's LVTTL or CMOS logic standards. Verify that the 0°C to +70°C operating range meets the environmental conditions of the target application, as extended temperature variants like the SN65LVDS389 may be necessary for harsher environments.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SNx5LVDS389 family of octal LVDS drivers from Texas Instruments. It shares functional similarities with the SN65LVDS389 but differs in the specified operating temperature range, being rated for commercial use rather than the extended industrial range. The family provides a standardized solution for converting parallel data streams into serial differential formats for long-distance transmission.

Drivers, Receivers, Transceivers Replacement Considerations

The SN65LVDS389DBTG4 serves as a pin-compatible alternative offering an extended temperature range of -40°C to +85°C. Verify that the thermal requirements of the application justify the substitution, as electrical characteristics remain largely identical between the commercial and industrial grade versions.
