SN75LVDS391PWR

Drivers, Receivers, Transceivers Overview

The SN75LVDS391PWR is a quad LVDS transmitter manufactured by Texas Instruments, designed for high-speed differential signaling compliant with the EIA/TIA-644 standard. It operates on a single 3V to 3.6V power supply, consuming approximately 26mA of quiescent current. The device supports data rates up to 630 Mbps with a typical propagation delay of less than 2.9 ns and output skew under 150 ps. It accepts LVTTL inputs and provides LVDS outputs in a 16-pin TSSOP package. The component functions within an industrial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides four independent low-voltage differential signal drivers for high-speed data transmission
• Accepts LVTTL logic inputs while delivering standardized LVDS outputs
• Features internal pull-down resistors on inputs and enable pins to ensure defined states during open-circuit conditions

Drivers, Receivers, Transceivers Applications

• High-speed serial data communication interfaces
• Point-to-point or multi-drop bus architectures requiring LVDS compliance
• Industrial control systems operating within extended temperature ranges

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' indicates the tape-and-reel packaging variant of the SN75LVDS391 series. Confirm that the operational temperature range aligns with the commercial/industrial grade (0°C to 70°C) rather than the extended grade (-40°C to 85°C). Ensure compatibility with existing PCB footprints for the 16-pin TSSOP package before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad LVDS driver is required for systems utilizing LVTTL source logic. It is suitable for applications needing moderate data rates up to 630 Mbps with low electromagnetic interference. Compare against the SN65LVDS391 if a wider temperature range (-40°C to 85°C) is necessary, as the SN75 variant is limited to 0°C to 70°C.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx5LVDS3xx family of high-speed differential line drivers from Texas Instruments. These devices implement the electrical characteristics of Low Voltage Differential Signaling (LVDS), reducing output voltage levels compared to 5V standards to lower power consumption and increase switching speed. The family includes quad, octal, and hex configurations to support various bus widths.

Drivers, Receivers, Transceivers Replacement Considerations

The SN65LVDS391 offers identical functionality but supports an extended temperature range of -40°C to 85°C. For pin-compatible alternatives, verify other quad LVDS transmitters from the same manufacturer that meet EIA/TIA-644 specifications.
