In the 74121, which is nonretriggerable, any triggers that come in before the end of the timing cycle are ignored.
When extremely critical timing is required, a quartz crystal can be used.
A comparator simply outputs a HIGH or LOW based on a comparison of the voltage levels at its input.
When the 74123, a retriggerable monostable multivibrator device, ends its timing cycle it must be started all over again.
Timing accuracy of more than eight significant digits can be easily achieved by using quartz crystals.
The 74S124 TTL chip is a voltage-controlled oscillator that will generate a specific frequency at Vout.
A multivibrator is a circuit that changes between two digital levels on a continuous, free-running basis or on demand.
A monostable multivibrator is commonly called a two shot.
