Description and Introduction

BiMOS II 8-BIT SERIAL-INPUT, LATCHED DRIVERS The part **UCN5841A** is manufactured by **ALLEGRO**. Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Type:** 8-Channel Serial Input, Power Darlington Driver  
- **Output Current:** 500mA per channel (sink)  
- **Output Voltage:** 50V  
- **Logic Input Voltage:** 5V (TTL/CMOS compatible)  
- **Serial Data Interface:** Shift register with latch  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package Type:** 18-Pin DIP (Dual In-Line Package)  

### **Descriptions:**  
The **UCN5841A** is a high-voltage, high-current Darlington transistor array designed for interfacing between low-level logic and high-power loads. It features an 8-bit serial-in, parallel-out shift register with latched outputs, making it suitable for driving relays, solenoids, lamps, and other inductive loads.  

### **Features:**  
- **8 Darlington Outputs** (500mA per channel)  
- **Built-in Suppression Diodes** for inductive load protection  
- **TTL/CMOS-Compatible Inputs**  
- **Serial Data Input with Latch** for easy microcontroller interfacing  
- **High-Voltage Outputs** (up to 50V)  
- **Thermal Shutdown Protection**  
- **Low Power Consumption**
