Description and Introduction

Dual High-Voltage, High-Current Peripheral Drivers The SN75471D is a dual peripheral driver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Configuration:** Dual-channel (two independent drivers)  
- **Output Type:** High-current Darlington transistor  
- **Output Current (per channel):** 500 mA (continuous), 1 A (peak)  
- **Output Voltage (Max):** 50 V  
- **Input Voltage (Logic High):** 2 V (min)  
- **Input Voltage (Logic Low):** 0.8 V (max)  
- **Supply Voltage (VCC):** 4.5 V to 36 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8 (D)  

### **Descriptions:**  
The SN75471D is designed for driving high-current loads such as relays, solenoids, and DC motors. It features built-in Darlington transistor pairs for improved current handling and includes input clamping diodes for inductive load protection.  

### **Features:**  
- **High-Voltage, High-Current Outputs**  
- **Integrated Clamp Diodes** for inductive load protection  
- **TTL/CMOS-Compatible Inputs**  
- **Wide Supply Voltage Range** (4.5 V to 36 V)  
- **Thermal Shutdown Protection** (prevents damage from overheating)  
- **Low Input Current Requirement**  

This device is commonly used in industrial control, automotive, and robotics applications where reliable switching of inductive loads is required.
