Description and Introduction

Dual Retriggerable Monostable Multivibrators 16-SOIC -40 to 85 The SN74AHC123ADRG4 is a dual retriggerable monostable multivibrator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Monostable Multivibrator  
- **Number of Circuits:** 2  
- **Output Type:** Push-Pull  
- **Voltage Supply Range:** 2 V to 5.5 V  
- **Propagation Delay (Max):** 13 ns at 5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-16  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74AHC123ADRG4 features two independent retriggerable monostable multivibrators.  
- Each multivibrator can be triggered by either a positive or negative edge.  
- The output pulse width is determined by external timing components (resistor and capacitor).  
- It supports a wide operating voltage range, making it suitable for various digital applications.  

### **Features:**  
- **Retriggerable Operation:** Allows pulse width extension by retriggering before the timeout.  
- **Wide Supply Voltage Range:** 2 V to 5.5 V for compatibility with multiple logic levels.  
- **Low Power Consumption:** Optimized for energy-efficient designs.  
- **High Noise Immunity:** Typical of AHC logic family.  
- **Schmitt-Trigger Inputs:** Allows for slow input transition handling.  

For detailed application information, refer to the official TI datasheet.

Application Scenarios & Design Considerations

Dual Retriggerable Monostable Multivibrators 16-SOIC -40 to 85

Alternative Part Number

  • 74AHC123APW,118 --: Same dual retriggerable monostable multivibrator function in AHC logic family, TSSOP package, direct functional equivalent from a different vendor.
  • MC74VHC123ADTR2G --: Dual retriggerable monostable multivibrator with similar AHC/VHC speed and drive characteristics, available in SOIC, good drop-in alternative.
  • CD74HC123E --: Same dual retriggerable monostable function from the same manufacturer but in the HC series and PDIP package, suitable when package and minor speed differences are acceptable.
