Description and Introduction

Quad 2-input positive-NAND buffers with open collector outputs The SN74LS38 is a quad 2-input NAND buffer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Quad 2-Input NAND Buffer  
- **Technology Family:** LS (Low-Power Schottky)  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Output Type:** Open-Collector  
- **Propagation Delay (Max):** 15 ns  
- **Power Dissipation (Max):** 22 mW per gate  
- **Input Current (Max):** 0.36 mA  
- **High-Level Output Current (Max):** -0.4 mA  
- **Low-Level Output Current (Max):** 8 mA  

### **Description:**  
The SN74LS38 is a quad 2-input NAND buffer with open-collector outputs, designed for use in digital logic applications. It provides four independent NAND gates, each with two inputs and one output. The open-collector outputs allow for wired-AND connections and interfacing with higher-voltage or higher-current circuits.  

### **Features:**  
- Open-collector outputs for bus-oriented applications  
- Low power consumption  
- High noise immunity  
- Compatible with TTL inputs  
- Standard pin configuration  

This device is commonly used in digital systems for logic buffering, signal inversion, and interfacing with external circuits.

Application Scenarios & Design Considerations

Quad 2-input positive-NAND buffers with open collector outputs

Alternative Part Number

  • DM74LS38N --: Pin-compatible quad 2-input NAND buffer with open-collector outputs in the same LS logic family, direct functional drop-in replacement.
  • MC74LS38N --: Equivalent 74LS38 open-collector NAND buffer with identical logic function and DIP pinout, widely available second source.
  • SN74LS37N --: Same LS family quad 2-input NAND buffer with open-collector outputs; slightly different drive rating but functionally interchangeable in most designs.
  • 74LS38PC --: Direct functional equivalent quad 2-input NAND open-collector gate in DIP, widely available second source.
