Description and Introduction

Dual Retriggerable Monostable Multivibrators 16-SOIC -40 to 85 The **SN74AHC123ADG4** is a dual retriggerable monostable multivibrator manufactured by **Texas Instruments (TI)**.  

### **Key Specifications:**  
- **Technology Family:** AHC  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Speed Operation:** tpd ≈ 7.5 ns (typical at 5 V)  
- **Low Power Consumption:** ICC ≈ 2 µA (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (DG4) – 16-pin  

### **Descriptions:**  
- **Dual Monostable Multivibrator:** Contains two independent retriggerable/resettable monostable multivibrators.  
- **Retriggerable Function:** Allows extending the output pulse by retriggering before the initial pulse ends.  
- **Reset Capability:** Features a direct reset input for immediate pulse termination.  
- **Wide Pulse Control:** Adjustable pulse width via external resistor (Rext) and capacitor (Cext).  

### **Features:**  
- **Schmitt-Trigger Inputs:** Allows slow input transition and better noise immunity.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **Overvoltage-Tolerant Inputs:** Supports voltages up to 5.5 V regardless of VCC.  
- **ESD Protection:** Exceeds 2000 V (HBM) and 1000 V (CDM).  

This device is commonly used in applications requiring precision timing, such as pulse stretching, delay generation, and sequential timing circuits.
