Dual Monostable Multivibrator The TC74VHC123AFK is a dual retriggerable monostable multivibrator manufactured by Toshiba. Below are the key specifications, descriptions, and features from Ic-phoenix technical data files:
### **Specifications:**
- **Supply Voltage Range (VCC):** 2.0V to 5.5V
- **High-Speed Operation:** tPD = 4.5 ns (typical) at 5V
- **Low Power Consumption:** ICC = 2 μA (max) at Ta = 25°C
- **Output Current:** ±8 mA (min) at VCC = 4.5V
- **Operating Temperature Range:** -40°C to +85°C
- **Package Type:** SSOP-16
### **Descriptions:**
- The TC74VHC123AFK is a dual monostable multivibrator with retriggerable and reset capabilities.
- It is designed using high-speed CMOS technology, ensuring low power consumption while maintaining high noise immunity.
- Each multivibrator has independent trigger inputs (A, B), clear inputs (CLR), and outputs (Q, Q̅).
- The output pulse width can be controlled by external timing components (resistor and capacitor).
### **Features:**
- **Retriggerable Function:** Allows the output pulse width to be extended by reapplying a trigger signal.
- **Reset Capability:** The clear input (CLR) can terminate the output pulse prematurely.
- **Wide Operating Voltage Range:** Supports 2.0V to 5.5V, making it compatible with TTL and CMOS logic levels.
- **High Noise Immunity:** Features typical noise margins of 28% of VCC.
- **Schmitt Trigger Inputs:** Ensures stable operation even with slow input transitions.
