CD74HC123E (74HC123)

Description:

The CD74HC123E is a high-speed CMOS dual retriggerable monostable multivibrator with reset. This device can be triggered from either the rising or falling edge of an input pulse and is capable of generating precise output pulses. The duration of the output pulse can be controlled by external timing components (resistor and capacitor) and can be retriggered to extend the pulse duration. The CD74HC123E features low power consumption, high noise immunity, and a wide operating voltage range, making it ideal for a variety of timing and pulse generation applications.
