### **Descriptions:**
- The SN74LV123A is a dual retriggerable monostable multivibrator with clear functionality.
- Each multivibrator features independent **A (active-low)** and **B (active-high)** trigger inputs, a **clear (active-low)** input, and complementary **Q (active-high)** and **Q̅ (active-low)** outputs.
- It is designed for pulse-width control in digital systems, offering precise timing adjustments via external resistors and capacitors.
- The device operates over a wide voltage range, making it suitable for mixed-voltage applications.
### **Features:**
- **Dual Monostable Multivibrator:** Two independent retriggerable one-shots in a single package.
- **Retriggerable Operation:** Allows extending the output pulse by reapplying a trigger before the pulse ends.
- **Wide Operating Voltage:** Supports 2 V to 5.5 V, compatible with 3.3 V and 5 V systems.
- **Schmitt-Trigger Inputs:** Provide hysteresis for improved noise immunity.
- **Low Power Consumption:** Suitable for battery-operated devices.
- **High Output Drive:** Capable of driving heavy loads.
- **ESD Protection:** Exceeds 2000 V (HBM) and 1000 V (CDM).
