Description and Introduction

DUAL MONOSTABLE MULTIVIBRATORS The SN74LV221APWR is a dual monostable multivibrator (one-shot) manufactured by Texas Instruments (TI).  

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

### **Descriptions:**  
- The SN74LV221APWR 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 is designed for 2 V to 5.5 V operation, making it suitable for low-voltage applications.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Low Power Consumption:** Ideal for battery-operated devices  
- **Retriggerable Operation:** Allows pulse-width extension  
- **Schmitt-Trigger Inputs:** Noise immunity  
- **High-Speed CMOS Technology:** Ensures fast switching  
- **ESD Protection:** Exceeds 2000 V per JESD 22  

This device is commonly used in timing applications, pulse generation, and system reset circuits.

Application Scenarios & Design Considerations

DUAL MONOSTABLE MULTIVIBRATORS

Alternative Part Number

  • MC74VHC221ADTR2G --: Dual monostable multivibrator in the same logic family with similar supply voltage range and TSSOP package, direct functional replacement.
  • 74VHC221AMTCX --: Dual retriggerable monostable multivibrator with compatible 2-5.5V operation and TSSOP footprint, suitable drop-in alternative.
  • CD74HC221E --: Dual monostable multivibrator from TI's HC family offering similar timing functions, though in DIP package requiring layout adaptation.
  • 74LVC221APW,118 --: Dual retriggerable monostable multivibrator in TSSOP, comparable 3.3V logic family and pin-compatible footprint.
