Description and Introduction

Quad 2-input positive-AND gates with open collector outputs The SN74LS09NSR is a quad 2-input positive AND gate manufactured by Texas Instruments. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** AND 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 Time (tpd):** 15ns (typical)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74LS09NSR is a member of the 74LS logic family, featuring low-power Schottky technology.  
- It contains four independent 2-input AND gates with open-collector outputs.  
- Open-collector outputs allow for wired-AND connections and interfacing with higher voltage levels.  

### **Features:**  
- **Open-Collector Outputs:** Enable wired-AND logic and external pull-up resistors.  
- **Low Power Consumption:** Typical power dissipation of 2mW per gate.  
- **High Noise Immunity:** Standard for LS-TTL logic.  
- **Wide Operating Voltage Range:** Compatible with TTL levels.  
- **Surface-Mount Package (SOIC-14):** Suitable for compact PCB designs.

Application Scenarios & Design Considerations

Quad 2-input positive-AND gates with open collector outputs

Alternative Part Number

  • DM74LS09N --: Same quad 2-input AND gate with open-collector outputs in the LS logic family, directly interchangeable in most designs.
  • 74LS09PC --: Equivalent LS-series quad open-collector AND gate from the same manufacturer, differing only in package and naming.
  • SN74LS08N --: Quad 2-input AND gate in the same LS family; usable substitute when open-collector outputs are not strictly required.
  • MC74LS09N --: Pin-compatible quad 2-input AND gate with open-collector outputs from an established LS logic line, suitable as a drop-in functional substitute.
