Description and Introduction

Dual Retriggerable Monostable Multivibrators The SN74AHC123APWR is a dual retriggerable monostable multivibrator manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** TSSOP-16  
- **Pb-Free:** Yes (RoHS compliant)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Speed Operation:** tpd ≈ 7.5 ns (typical at 5 V)  
- **Low Power Consumption:** ICC ≈ 1 μA (max)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions & Features:**  
- Dual retriggerable monostable multivibrator with Schmitt-trigger inputs.  
- Features independent clear inputs for each multivibrator.  
- Output pulse width is adjustable using external timing components (resistor and capacitor).  
- Retriggerable for pulse-width extension.  
- Inputs accept voltages higher than VCC for interfacing with 5 V logic.  
- Balanced propagation delays for improved noise immunity.  
- Supports partial power-down mode (Ioff circuitry disables outputs when VCC = 0 V).  

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

Application Scenarios & Design Considerations

Dual Retriggerable Monostable Multivibrators

Alternative Part Number

  • MC74VHC123ADTR2G --: Dual retriggerable monostable multivibrator in TSSOP-16, functionally equivalent to the SN74AHC123A with similar AHC/VHC speed family and Pb-free packaging.
  • 74AHC123APW,118 --: Direct AHC-family dual retriggerable monostable multivibrator in TSSOP-16, same logic function and supply range, Pb-free and widely available.
  • CD74HC123PWR --: HC-family dual retriggerable monostable multivibrator in TSSOP-16 from the same vendor, pin-compatible and Pb-free, usable where slightly lower speed is acceptable.
