MM74C221
Dual Monostable Multivibrator
General Description
The MM74C221 dual monostable multivibrator is a mono-
lithic complementary MOS integrated circuit. Each multivi-
brator 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 CEXT and REXT. The pulse
width is stable over a wide range of temperature and VCC.
Pulse stability will be limited by the accuracy of external
timing components. The pulse width is approximately
defined by the relationship tW(OUT) ≈ CEXT REXT. For fur-
ther information and applications, see AN-138.
