Description and Introduction

Quadruple 2-Input Positive-AND Gates The SN74LS08DR is a quad 2-input AND gate IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** AND Gate  
- **Number of Circuits:** 4  
- **Number of Inputs per Gate:** 2  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Propagation Delay Time (Max):** 15 ns at 5V  
- **Low-Level Output Current (Max):** 8 mA  
- **High-Level Output Current (Max):** -0.4 mA  
- **Package / Case:** SOIC-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74LS08DR is part of the 74LS series, which uses low-power Schottky (LS) technology.  
- It contains four independent 2-input AND gates in a single package.  
- Designed for general-purpose logic applications.  

### **Features:**  
- **Low Power Consumption:** Typical power dissipation of 2 mW per gate.  
- **TTL-Compatible Inputs:** Works with standard TTL logic levels.  
- **High Noise Immunity:** Improved noise margins compared to standard TTL.  
- **Wide Operating Voltage Range:** Suitable for 5V systems.  
- **Surface-Mount Package (SOIC-14):** Compact and suitable for PCB applications.  

This IC is commonly used in digital logic circuits, computing systems, and control applications.

Application Scenarios & Design Considerations

Quadruple 2-Input Positive-AND Gates

Alternative Part Number

  • DM74LS08M --: Quad 2-input AND gate in the same LS TTL family with identical logic function and pinout, available in SOIC package; a direct functional drop-in from a second source.
  • 74LS08D --: Standard quad 2-input AND gate in LS TTL, SOIC-14 package, same pinout and electrical characteristics; widely stocked alternative from a different vendor.
  • MC74LS08DR2G --: Quad 2-input AND gate LS TTL device in SOIC-14, functionally and pin-compatible with the original, offered as an active second-source option.
  • SN74HC08DR --: Quad 2-input AND gate in HC CMOS family from the same manufacturer; pin-compatible and usable where LS drive/speed requirements are not critical, though input thresholds differ.
