MM54C221 MM74C221 Dual Monostable Multivibrator
General Description
The MM54C221 MM74C221 dual monostable multivibrator
is a monolithic complementary MOS integrated circuit Each
multivibrator features a negative-transition-triggered input
and a positive-transition-triggered input either of which can
be used as an inhibit input and a clear input
Once fired the output pulses are independent of further
transitions of the A and B inputs and are a function of the
external timing components C
EXT
and R
EXT
The pulse
width is stable over a wide range of temperature and V
CC
Pulse stability will be limited by the accuracy of external
timing components The pulse width is approximately de-
fined by the relationship t

AC Parameters are guaranteed by DC correlated testing
Note 1
``Absolute Maximum Ratings'' are those values beyond which the safety of the device cannot be guaranteed Except for ``Operating Temperature Range''
they are not meant to imply that the devices should be operated at these limits The table of ``Electrical Characteristics'' provides conditions for actual device
operation
Note 2
Capacitance is guaranteed by periodic testing
