Functional Features

• Dual monostable multivibrator with independent trigger and reset inputs.
• Provides stable and accurate timing pulses.
• Monostable 1 and Monostable 2 can be triggered and reset independently.
• Wide supply voltage range allows for versatile applications.

Advantages and Disadvantages

Advantages

• Accurate and stable timing pulses.
• Independent trigger and reset inputs for each monostable.
• Wide supply voltage range for versatile applications.

Disadvantages

• Limited number of monostables (only two).
• Not suitable for applications requiring a large number of timing pulses.

Working Principles

The CD14538BM96 operates based on the principles of monostable multivibrators. When triggered, each monostable generates a pulse of fixed duration determined by the external resistor and capacitor connected to its respective pins. The output pulse width is independent of the trigger pulse duration.
