Description and Introduction

EIGHT DARLINGTON ARRAYS The ULQ2001A is a high-voltage, high-current Darlington transistor array manufactured by STMicroelectronics.  

### **Specifications:**  
- **Configuration:** 7-channel Darlington array  
- **Output Voltage (VCE):** 50V  
- **Output Current (IC):** 500mA per channel  
- **Input Voltage (VIN):** 30V  
- **Input Current (IIN):** 2.5mA (max per channel)  
- **Clamp Diodes:** Integrated for inductive load protection  
- **Logic Compatibility:** TTL, CMOS, PMOS  
- **Package Options:** DIP-16, SO-16  

### **Descriptions and Features:**  
- Designed for interfacing between low-level logic and high-power loads.  
- Each channel consists of open-collector Darlington pairs with common-emitter configuration.  
- Built-in suppression diodes for switching inductive loads.  
- Suitable for relay, lamp, and motor drivers.  
- High-voltage outputs with common-cathode clamp diodes.  
- Inputs are pinned opposite outputs to simplify PCB layout.  

This device is commonly used in industrial, automotive, and consumer applications requiring robust switching capabilities.
