Description and Introduction

DUAL 4-INPUT POSITIVE-NAND GATES WITH OPEN-COLLECTOR OUTPUTS The SN7422N is a dual 4-input positive-NAND buffer manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** NAND Gate  
- **Number of Circuits:** 2  
- **Number of Inputs per Gate:** 4  
- **Supply Voltage (VCC):** 4.75V to 5.25V (standard TTL levels)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Propagation Delay:** Typically 10ns (varies with conditions)  
- **Output Type:** Totem Pole  
- **Package Type:** PDIP-14 (Plastic Dual In-line Package)  
- **Mounting Type:** Through-Hole  

### **Description:**  
The SN7422N is a TTL (Transistor-Transistor Logic) device containing two independent 4-input NAND gates with buffered outputs. It is designed for general-purpose logic applications.  

### **Features:**  
- **High-Speed Operation:** Compatible with standard TTL switching speeds.  
- **Buffered Outputs:** Provides improved noise immunity and drive capability.  
- **Wide Operating Voltage Range:** Supports standard 5V TTL logic levels.  
- **DIP Packaging:** Easy to use in breadboard and through-hole PCB applications.  

For exact electrical characteristics, refer to the official Texas Instruments datasheet.
