Description

The CD74HC123PWR is a high-speed CMOS dual retriggerable monostable multivibrator designed for various timing applications. It features two independent monostable circuits capable of generating output pulses of programmable width in response to input trigger signals.
Key specifications include a wide operating voltage range (2V to 6V), high-speed operation (up to 8 MHz), and low power consumption. The output pulse width is determined by external resistors and capacitors, making it versatile for producing precise timing intervals.
The device's retriggerable capability allows it to extend the output pulse when a new trigger occurs before the current pulse ends. It is commonly used in applications such as timer circuits, pulse-width modulation, frequency dividers, and signal conditioning.
The CD74HC123PWR is provided in a surface-mount package (TSSOP), making it suitable for compact designs. Overall, it is a reliable choice for engineers needing flexible timing solutions in digital circuits.
