Dual Monostable Multivibrator
The TC74HC221A is a high speed
CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the
CMOS low power dissipation.
There are two trigger inputs, A input (negative edge), and B input (positive edge).
These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs.
This device may also be triggered by using CLR input (positive edge).
After triggering, the output stays in a MONOSTABLE state for a time period determined...
