Working Principles

The 74HCT123PW-Q100,11 is a dual retriggerable monostable multivibrator. It generates an output pulse of a fixed duration when triggered by a positive edge at the Trigger (A) input. The output pulse width can be adjusted using external timing components connected to the resistor-capacitor (RC) network. The multivibrator can be retriggered by a positive edge at the Retrigger (B) input, extending the output pulse width. The Clear (CLR) input resets the output to its inactive state.

Detailed Application Field Plans

• Timing and delay circuits in digital systems
• Pulse shaping and waveform generation
• Frequency division and counting circuits
• Precision timing in communication systems
• Control signal generation in industrial automation
