Description

The CD54HCT123F3A is a dual retriggerable monostable multivibrator IC, part of the HCT (High Speed CMOS TTL compatible) family. It operates on a supply voltage range of 4.5V to 5.5V and is designed for high-speed operation, making it suitable for a variety of timing applications. The device features two independent monostable circuits that can generate a single output pulse in response to a trigger input, with the pulse width determined by an external resistor and capacitor.
Key characteristics include low power consumption, high noise immunity, and compatibility with standard TTL input levels. The CD54HCT123F3A is often used in applications such as pulse width modulation, timers, and frequency division. Additionally, its retriggerable feature allows for the adjustment of pulse width upon receiving new trigger signals before the output pulse expires. The device is available in various package options, making it versatile for different circuit designs.
