CMOS timing circuit for event counting

The CD4538 DIP Dual Retriggerable Precision Monostable Multivibrator is a CMOS IC that contains two independent monostable multivibrators, capable of generating precise output pulses with durations controlled by external components. Retriggerable operation allows continuous pulse generation in response to external triggers, making the CD4538 ideal for pulse width modulation, timing circuits, event counting, and frequency control applications. With a wide operating voltage range (3V to 18V) and low power consumption, it is perfect for embedded systems, measurement equipment, and digital control systems.
