DS3680DE4

Telecom Overview

The DS3680DE4 is a quad telephone relay driver manufactured by Texas Instruments. It integrates four independent drivers designed to control external relays in telecommunications applications. The device operates within a negative supply voltage range of -10 V to -60 V and draws a typical operating supply current of 4.4 mA. It features a 14-pin Small Outline Integrated Circuit (SOIC) package with a wide body, designated by the 'DE' suffix. The component supports an industrial temperature range from 0°C to +70°C and includes built-in transient protection for robust performance in noisy environments.

Telecom Feature Summary

• Integrates four independent high-current drivers specifically optimized for controlling telephone line relays
• Incorporates internal transient protection circuits to safeguard against voltage spikes on the telephone lines
• Utilizes differential input logic to ensure reliable signal reception in electrically noisy telecommunications environments

Telecom Applications

• Telecommunications switching equipment requiring multiple relay control channels
• PBX systems and voice processing units utilizing external relay interfaces
• Industrial communication gateways managing line switching operations

Telecom Procurement Notes

Verify the specific ordering suffix DE4 confirms the SOIC-14 package variant and lead-free manufacturing status. Confirm that the industrial temperature grade (0°C to +70°C) aligns with the target deployment environment requirements. Ensure compatibility with existing board layouts for the 14-pin small outline package dimensions before finalizing procurement orders.

Telecom Selection Notes

Select this component when a quad-channel relay driver solution is required for standard telephone interface voltages up to -60 V. Consider the SOIC-14 package constraints regarding thermal dissipation and PCB space availability. Evaluate the 4.4 mA supply current consumption against system power budget limitations compared to alternative low-power interface solutions.

Telecom Part Context

This part belongs to the DS3680 family of quad telephone relay drivers produced by Texas Instruments. The DE4 suffix specifically denotes the surface-mount SOIC-14 package configuration with lead-free composition. It serves as a functional equivalent to other variants in the series, such as the DIP or wider SOIC packages, tailored for automated assembly processes.

Telecom Replacement Considerations

The DS3680D is a direct pin-compatible substitute offering the same functionality in a standard SOIC-14 package. Verify that any replacement maintains the -10 V to -60 V operating voltage range and identical pinout configuration to ensure seamless integration without schematic modifications.
