Description and Introduction

HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAYS The ULN2011A is a high-voltage, high-current Darlington transistor array manufactured by Sprague.  

### **Specifications:**  
- **Configuration:** 7-channel Darlington transistor array  
- **Voltage Rating:** Up to 50V  
- **Current Rating:** 500mA per channel (sink capability)  
- **Input Compatibility:** TTL, CMOS, and PMOS logic levels  
- **Output Type:** Open-collector  
- **Package Type:** 16-pin DIP (Dual In-line Package)  
- **Features Built-in Suppression Diodes:** For inductive load protection  

### **Descriptions and Features:**  
- Designed for interfacing between low-level logic circuits and high-power loads.  
- Each channel includes a Darlington pair with a common emitter.  
- Integrated clamp diodes allow direct driving of inductive loads (relays, solenoids, stepper motors).  
- Suitable for applications requiring high-current sinking capability.  
- Used in relay drivers, lamp drivers, display drivers, and motor controllers.  

This information is based on the manufacturer's datasheet and technical documentation.
