Description and Introduction

Dual Retriggerable Monostable Multivibrators The **SN74LV123ADR** is a dual retriggerable monostable multivibrator (one-shot) manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Integrated Circuits (ICs)  
- **Type:** Monostable Multivibrator  
- **Number of Circuits:** 2  
- **Output Type:** Complementary  
- **Voltage - Supply:** 2V to 5.5V  
- **Propagation Delay:** 45ns (typical at 5V)  
- **Operating Temperature:** -40°C to 125°C  
- **Package / Case:** SOIC-16  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74LV123ADR is a dual retriggerable monostable multivibrator that generates a pulse with a duration determined by external timing components (resistor and capacitor).  
- It features independent clear inputs for each multivibrator and can be retriggered for extended pulse widths.  
- Suitable for applications requiring precise timing control, such as pulse stretching, delay generation, and debouncing.  

### **Features:**  
- **Wide Operating Voltage Range:** 2V to 5.5V  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **Retriggerable Operation:** Allows pulse-width extension  
- **Complementary Outputs:** Provides both Q and Q̅ outputs  
- **Schmitt-Trigger Inputs:** Ensures noise immunity  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This information is strictly factual and derived from the manufacturer's datasheet.

Application Scenarios & Design Considerations

Dual Retriggerable Monostable Multivibrators

Alternative Part Number

  • MC74VHC123ADG --: Dual retriggerable monostable multivibrator in SOIC-16 with similar 2V-5.5V supply range and logic-compatible inputs, a direct functional cross from another vendor.
  • CD74HC123E --: Same dual retriggerable monostable function from the same vendor but in the HC family and PDIP package, useful when a through-hole or alternate logic family is acceptable.
  • 74LVC1G123DP --: Single retriggerable monostable in a small TSSOP package with wide 1.65V-5.5V supply, suitable when only one channel is needed and board space is tight.
  • 74VHC123AMTCX --: Dual retriggerable monostable multivibrator with comparable propagation delays and output drive, pin-compatible in TSSOP-16 and suitable for drop-in replacement in most designs.
