SN65LVDS34DR

Drivers, Receivers, Transceivers Overview

The SN65LVDS34DR is a high-speed differential receiver manufactured by Texas Instruments, designed for LVDS signaling applications. It features two receivers with an integrated 110-ohm line termination resistor, classifying it within the LVDT series. The device supports a signaling rate of 400 Mbps and operates on a single 3.3-V supply voltage ranging from 3 V to 3.6 V. It accommodates a wide common-mode input voltage range of -4 V to 5 V and includes active failsafe circuitry to ensure a high-level output during signal loss. The component is housed in an SOIC-8 package and is characterized for operation between -40°C and +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates 110-ohm line termination resistors directly into the receiver to eliminate external components.
• Features active failsafe logic that drives the output high when the input signal is lost or disconnected.
• Provides a wide common-mode input voltage range compatible with 5-V PECL signals.

Drivers, Receivers, Transceivers Applications

• Point-to-point baseband data transmission over controlled impedance media.
• Conversion of ECL/PECL signals to LVTTL levels.
• High-speed digital communication interfaces requiring noise immunity.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'R' indicates taped and reeled carrier configuration. Confirm the package type corresponds to the SOIC (D) drawing. Ensure the part marking matches the LVDT34 designation to distinguish it from non-terminated variants. Check for RoHS compliance status and lead finish specifications such as NIPDAU before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model when internal termination is required for a two-channel LVDS application. Compare against the SN65LVDS34 if external termination is preferred or if cost reduction is prioritized over board space. Consider the SN65LVDT33 if four channels are needed instead of two. Verify that the operating temperature range meets the environmental requirements of the target system.

Drivers, Receivers, Transceivers Part Context

This component belongs to the SN65LVDS3x family of high-speed differential receivers. It shares functional similarities with the SN65LVDS33 but differs in channel count and termination integration. The DR suffix specifically denotes the SOIC-8 package variant supplied in tape and reel format for automated assembly processes.

Drivers, Receivers, Transceivers FAQ

What is the function of the active failsafe feature?

The active failsafe circuit ensures the output remains at a high level if the input signal is lost due to disconnected cables, shorted lines, or powered-down transmitters, preventing noise from being interpreted as valid data.

How does the SN65LVDS34 handle common-mode voltage?

It supports a common-mode input voltage range of -4 V to 5 V, allowing compatibility with 5-V PECL signals without requiring additional resistor divider networks.
