Overview
The 74HCT123PW,118 is a dual retriggerable monostable multivibrator with reset, manufactured by Nexperia USA Inc. This component is part of the 74HCT series and is designed to provide flexible timing and pulse generation capabilities. It is particularly suited for applications requiring adjustable pulse widths and high noise immunity.
The device features two independent monostable multivibrators, each capable of generating output pulses with widths determined by external resistor and capacitor (R and C) combinations. The pulse width can be extended by retriggering the inputs, and the output pulse can be terminated at any time using the reset input.
