Working Principles

The CD74HCT123M96G4 is a dual retriggerable monostable multivibrator. It generates a single output pulse of a specific width when triggered by an input signal. The pulse width is determined by the external resistor-capacitor (RC) timing components connected to the RCext pin. The multivibrator can be retriggered during the output pulse, extending its duration.

Detailed Application Field Plans

1. Timing Control: The CD74HCT123M96G4 can be used in applications requiring precise timing control, such as clock synchronization, data sampling, and signal delay circuits.
2. Pulse Generation: It is suitable for generating accurate and adjustable pulses in applications like frequency dividers, pulse-width modulation, and waveform shaping.
3. Sequential Logic: The multivibrator can be utilized in sequential logic circuits, including flip-flops, counters, and shift registers, to control the timing and sequencing of operations.
