Description and Introduction

EIGHT DARLINGTON ARRAYS The ULQ2804A is a high-voltage, high-current Darlington transistor array manufactured by STMicroelectronics (STM). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Configuration:** 8-channel Darlington transistor array  
- **Output Voltage:** 50V (max)  
- **Output Current:** 500mA per channel (max)  
- **Input Voltage:** 5V TTL/CMOS compatible  
- **Input Current:** 2.5mA (max)  
- **Power Dissipation:** 2.25W (total package)  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package:** DIP-18, SO-18  

### **Descriptions:**  
- The ULQ2804A consists of eight NPN Darlington pairs with common emitters, featuring high-voltage outputs with integrated suppression diodes for inductive loads.  
- Designed for interfacing between low-voltage logic (TTL/CMOS) and high-current/high-voltage peripherals such as relays, solenoids, and lamps.  
- Includes built-in freewheeling diodes for inductive load protection.  

### **Features:**  
- **High-Voltage Outputs:** Up to 50V per channel.  
- **High-Current Capability:** 500mA continuous per channel.  
- **Integrated Clamp Diodes:** For switching inductive loads.  
- **TTL/CMOS Compatible Inputs:** Allows direct interfacing with logic circuits.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  
- **Common Emitter Configuration:** Simplifies circuit design.  

This information is based solely on the manufacturer's datasheet for the ULQ2804A.
