74HC423 ,Dual Retriggerable Monostable Multivibrator – SOP-16, 2V-6V Operating Voltage

The 74HC423 is a high-speed CMOS dual retriggerable monostable multivibrator with reset, designed for applications requiring pulse width control. The circuit features two independent monostable multivibrators, each with a retriggering capability that allows the pulse width to be extended by subsequent triggers. The output pulse width is determined by an external resistor (R_EXT) and capacitor (C_EXT). With a wide operating voltage range of 2.0V to 6.0V, the 74HC423 offers low power dissipation, high noise immunity, and Schmitt-trigger action on all inputs (except the reset input). It is commonly used in pulse generation, delay circuits, frequency timers, and waveform shaping applications. The 74HC423 provides direct reset functionality, allowing the output to be terminated at any time. It is packaged in a SOP-16 surface-mount package, making it suitable for high-density circuit designs.
