The 74HC123D is an integrated circuit (IC) component that belongs to the 74HC family. It is a dual retriggerable monostable multivibrator, also known as an "Astable Multivibrator." This IC is widely used in various applications like timers, waveform generation, pulse shaping, and frequency division. Below are the key features and an overview of the 74HC123D:
1. Dual Re-Triggerable Monostable Multivibrator: The 74HC123D consists of two identical independent monostable multivibrators in a single package. This feature enables the generation of two separate time delays triggered by different input signals.
2. Wide Operating Voltage Range: It operates within a wide voltage range, typically from 2V to 6V. This makes it compatible with different power supply systems.
3. Schmitt-Trigger Inputs: The inputs of the 74HC123D have Schmitt-trigger characteristics. This ensures better noise immunity and helps in proper signal conditioning.
4. Adjustable Time Delay: The time delay of each multivibrator can be easily adjusted using an external resistor (Rext) and capacitor (Cext) connected to designated pins. This flexibility allows you to customize and achieve the desired time delay according to your application requirements.
5. High-Speed Operation: It has a high-speed operation capability, making it suitable for applications that require precise timing and quick response
