Description and Introduction

QUAD 1.5 A DARLINGTON SWITCHES The ULN2069B is a high-voltage, high-current Darlington transistor array manufactured by STMicroelectronics (ST) and formerly by Sprague.  

### **Specifications:**  
- **Configuration:** 4-channel Darlington array  
- **Output Current (per channel):** 1.5A (peak)  
- **Output Voltage (Max):** 50V  
- **Input Voltage (Logic Compatible):** 5V TTL/CMOS  
- **Input Current (per channel):** ~2.7mA  
- **Saturation Voltage (Vce(sat)):** ~1.1V (typical at 350mA)  
- **Integrated Freewheeling Diodes:** Yes (for inductive load protection)  
- **Package:** 16-pin DIP (Dual In-line Package)  

### **Descriptions and Features:**  
- Designed for driving high-current loads such as relays, solenoids, lamps, and stepper motors.  
- Each channel consists of a Darlington pair with common-emitter configuration.  
- Includes built-in suppression diodes for inductive kickback protection.  
- TTL/CMOS compatible inputs for easy interfacing with microcontrollers and logic circuits.  
- High-voltage and high-current capability suitable for industrial and automotive applications.  
- Robust construction for reliable switching performance.  

This device is commonly used in applications requiring multiple high-power switching operations with minimal external components.
