The IC component TC74HC123APNEWF is a high-speed CMOS dual retriggerable monostable multivibrator with reset. It is commonly used in electronic circuits for time delay applications and pulse generation. This component is manufactured by Toshiba and belongs to the HC series.
Key features of the TC74HC123APNEWF include:
1. Dual Monostable Multivibrators: The IC contains two monostable multivibrators that can be triggered independently. Each section has a similar internal architecture consisting of trigger inputs, output pins, and timing components.
2. High-Speed Operation: TC74HC123APNEWF is designed for high-speed operation, making it suitable for applications requiring precise timing and fast response. The typical propagation delay for this component is in the range of a few nanoseconds.
3. Retriggerable Operation: Unlike traditional monostable multivibrators, the TC74HC123APNEWF can be retriggered during the timing cycle. The timing cycle gets extended whenever a trigger input is received within a specific time window after the initial trigger. This retriggerability allows for flexible and adjustable timing sequences.
4. Wide Range of Timing Capacitors: The IC has a wide timing capacitor selection range, which provides flexibility in choosing different timing periods. The timing capacitor value can be in the range of a few picofarads to several microfarads, allowing for a wide range of time delays
