Description and Introduction

Quad 2-input positive-NAND buffers with open collector outputs The SN74LS38DR is a quad 2-input NAND buffer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** NAND Gate  
- **Number of Circuits:** 4  
- **Number of Inputs per Gate:** 2  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **High-Level Output Current (IOH):** -0.4mA  
- **Low-Level Output Current (IOL):** 8mA  
- **Propagation Delay (tpd):** 15ns (typical)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** SOIC-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74LS38DR is a quad 2-input NAND buffer with open-collector outputs.  
- It is part of the 74LS series, which is based on low-power Schottky (LS) technology.  
- Open-collector outputs allow for wired-AND logic configurations and driving higher loads.  

### **Features:**  
- Open-collector outputs for bus-oriented applications  
- Low power consumption  
- High noise immunity  
- Standard TTL switching voltages  
- Compatible with most TTL families  

For detailed electrical characteristics and application notes, refer to the official TI datasheet.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • DM74LS38M --: Same 74LS38 quad 2-input NAND buffer with open-collector outputs, SOIC-14 package, direct functional and pin-compatible replacement.
  • 74LS38D --: Equivalent 74LS38 open-collector NAND buffer in SOIC-14, same logic function and electrical characteristics as the original.
  • SN74LS38D --: Same TI 74LS38 device in SOIC-14 without the tape-and-reel suffix, identical die and specifications, suitable when reel packaging is not required.
