pulse one period) on the application of each new
trigger pulse. For operation in the non-triggerable
mode, Q is connected to –TR when leading-edge
triggering (+ TR) is used or Q is connected to + TR
when trailing-edge triggering (– TR) is used. The time
period (T) for this multivibrator can be approximated
by T
a function of R
fig. 8. Values of T vary from unit to unit and as a func-
tion of voltage, temperature, and R
value of external resistance, R
Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.
