Description and Introduction

Quad 2-input positive-NAND buffers with open collector outputs The SN7438D is a quad 2-input positive-NAND buffer manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Type:** Quad 2-Input NAND Buffer  
- **Technology Family:** TTL (Transistor-Transistor Logic)  
- **Supply Voltage Range:** 4.75V to 5.25V (standard 5V operation)  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  
- **Propagation Delay Time:** Typically 22ns at 5V  
- **Output Current (High/Low):** -800µA / 16mA  
- **Package Type:** SOIC (Small Outline Integrated Circuit) - 14-pin  
- **Mounting Type:** Surface Mount  

### **Description:**  
The SN7438D is a quad 2-input NAND buffer with open-collector outputs, designed for bus-oriented applications. It provides high sink current capability and is commonly used in digital logic circuits.  

### **Features:**  
- **Open-Collector Outputs:** Allows wired-AND connections for bus applications.  
- **High Sink Current:** 16mA per output for driving loads.  
- **TTL-Compatible Inputs:** Ensures compatibility with standard TTL logic levels.  
- **Wide Operating Voltage:** Supports standard 5V logic systems.  
- **Low Power Consumption:** Typical power dissipation of 32mW.  

This information is based on the manufacturer's datasheet for the SN7438D.
