Description and Introduction

BCD-to-Decimal Decoders/Drivers 16-PDIP 0 to 70 The SN74LS445N is a BCD to decimal decoder/driver manufactured by Texas Instruments (TI). Below are the factual details from Ic-phoenix technical data files:  

### **Specifications:**  
- **Logic Type:** BCD to Decimal Decoder/Driver  
- **Technology Family:** LS (Low-Power Schottky)  
- **Number of Bits:** 4 (BCD input)  
- **Number of Outputs:** 10 (Decimal outputs, active-low)  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP (Plastic Dual In-Line Package)  
- **Package Size:** 16-pin  
- **Output Type:** Open-Collector  
- **Propagation Delay (Max):** 30 ns  
- **Current - Output High, Low:** 15mA, 24mA  

### **Descriptions:**  
- The SN74LS445N is designed to convert a 4-bit Binary-Coded Decimal (BCD) input into a corresponding active-low decimal output.  
- It features open-collector outputs, allowing for direct drive of common-cathode displays or other loads.  
- Suitable for applications such as display driving, instrumentation, and control systems.  

### **Features:**  
- **Active-Low Outputs:** Each of the 10 outputs is low when selected.  
- **High-Voltage Outputs:** Capable of driving up to 15V loads.  
- **Lamp Test Input:** Allows all outputs to be tested by forcing them low.  
- **Open-Collector Outputs:** Enable wired-OR connections and interfacing with higher-voltage circuits.  
- **Low Power Consumption:** Typical of LS-series logic.  

This information is based solely on the manufacturer's datasheet and specifications.
