Description and Introduction

High-Voltage, High-Current Darlington Transistor Arrays The SN75469DR is a peripheral driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SN75469DR  
- **Type:** Peripheral Driver  
- **Package:** SOIC (16-pin)  
- **Output Type:** Open Collector  
- **Output Current:** 500mA (per channel)  
- **Supply Voltage (VCC):** 4.5V to 36V  
- **Input Voltage (VIH):** 2V (min)  
- **Input Voltage (VIL):** 0.8V (max)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The SN75469DR is a dual peripheral driver designed for interfacing between low-level logic and high-power loads. It features open-collector outputs with high current capability, making it suitable for driving relays, solenoids, and other inductive loads.  

### **Features:**  
- **Dual-Channel Driver:** Two independent drivers in one package.  
- **High Current Output:** Capable of sinking up to 500mA per channel.  
- **Wide Voltage Range:** Operates from 4.5V to 36V.  
- **Open-Collector Outputs:** Allows flexible interfacing with different loads.  
- **TTL/CMOS Compatible Inputs:** Works with standard logic levels.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **ESD Protection:** Enhanced reliability in harsh environments.  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

High-Voltage, High-Current Darlington Transistor Arrays

Alternative Part Number

  • ULN2003ADR --: Seven-channel Darlington array in SOIC-16, functionally similar high-voltage/high-current sink driver and widely available drop-in style replacement.
  • MC1413BDR2G --: Seven-channel Darlington transistor array in SOIC-16 with comparable ratings, a common second-source alternative to the SN75469 series.
  • ULQ2003ADR --: Automotive-grade seven-channel Darlington array in SOIC-16, same package and function with higher voltage rating for robust designs.
