SN75471DR

Buffers, Drivers, Receivers, Transceivers Overview

The SN75471DR is a dual peripheral driver manufactured by Texas Instruments in an 8-pin SOIC package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature from 0°C to 70°C. The device features TTL-compatible diode-clamped inputs and provides high-voltage outputs capable of withstanding up to 70 V without latch-up after conducting 300 mA. It delivers continuous collector currents up to 400 mA and peak currents up to 500 mA, making it suitable for high-current peripheral applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features internal logic gates (AND) connected to NPN output transistors for combined logic and power driving capabilities.
• Includes diode-clamped inputs that provide protection against transient voltages and ensure TTL compatibility.
• Designed with robust output stages that prevent latch-up at high off-state voltages even after high current conduction.

• High-speed logic buffers
• Power drivers
• Relay drivers
• Lamp drivers
• MOS drivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the tape-and-reel packaging format containing 2500 units per reel. Confirm the lead finish is NIPDAU and the moisture sensitivity level is Level-1. Ensure the procurement matches the active production status and the standard commercial temperature range requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a system requires integrated logic gating alongside high-voltage and high-current output driving. It serves as a functional alternative to the SN75451B and SN75461 series, offering higher breakdown voltage tolerance at the cost of slightly slower switching speeds compared to the SN75451B.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN7547x series of dual peripheral drivers, which also includes the SN75472 (NAND) and SN75473 (OR). These devices are designed for systems needing higher breakdown voltages than previous generations, utilizing a plastic DIP or SOIC construction with copper lead frames for improved thermal performance and reliability.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Functionally interchangeable with SN75451B and SN75461 series drivers. Note that SN75451B offers faster switching speeds, while SN75471 provides higher breakdown voltage capability.
