DUAL MONOSTABLE MULTIVIBRATOR. RETRIGGERBLE/NON-RETRIGGERBLE The TC74VHC123 is a dual retriggerable monostable multivibrator manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:
### **Specifications:**
- **Supply Voltage Range (VCC):** 2.0V to 5.5V
- **High-Speed Operation:** tPD = 4.5 ns (typ.) at VCC = 5V
- **Low Power Consumption:** ICC = 2 μA (max) at Ta = 25°C
- **Output Current:** ±8 mA (min) at VCC = 5V
- **Operating Temperature Range:** -40°C to +85°C
- **Input Levels:** CMOS level compatible (TTL compatible at VCC = 5V)
- **Package Options:** SOP-16, TSSOP-16
### **Descriptions:**
- The TC74VHC123 is a dual retriggerable monostable multivibrator with reset functionality.
- Each multivibrator features independent trigger and reset inputs.
- The output pulse width is determined by external timing components (resistor and capacitor).
- It is designed for high-speed CMOS applications while maintaining low power consumption.
### **Features:**
- **Retriggerable Operation:** Allows extension of the output pulse by reapplying a trigger.
- **Reset Function:** Immediate termination of the output pulse via the reset input.
- **Wide Operating Voltage:** Supports 2.0V to 5.5V, making it suitable for mixed-voltage systems.
- **High Noise Immunity:** CMOS technology ensures stable operation in noisy environments.
- **Pin-to-Pin Compatible:** Direct replacement for standard 74-series logic devices.
