Functional Features

• Retriggerable monostable multivibrator with an active-low reset input (CLR).
• Generates a stable output pulse width based on the external timing components.
• Can be triggered by either a positive or negative edge transition on the trigger input (TRIG).
• Provides a non-retriggerable output pulse when the trigger input is held low for a specified time.
• Offers a wide operating voltage range, making it suitable for various digital applications.

Advantages and Disadvantages

Advantages: - High-speed operation due to CMOS technology. - Retriggerable feature allows flexibility in generating precise time delays. - Wide supply voltage range enables compatibility with different systems.

Disadvantages: - Limited maximum operating temperature of +125°C. - Requires external timing components for accurate pulse width generation.

Working Principles

The 74HCT423PW,112 operates as a retriggerable monostable multivibrator. When triggered by an edge transition on the TRIG input, the IC generates an output pulse whose width is determined by the external timing components connected to the RC pin. The output pulse remains stable until the next trigger occurs or the CLR input is activated.
