Power Down Mode
During a rapid power-down conditiona, as would
occur with a power supply short circuit or with a
poorlyfilteredpower supply, theenergy stored inC
X
could discharge intoPin 2 or 14. To Avoid possible
devicedamage in thismode,when C
X
is
0.5micro-
farad,a aprotection diode witha 1Ampere or higher
rating (1N5395 or equivalent) and a separate
groundreturn for C
X
should be provided as shown
in Fig. 1
An alternate protection method is shown in Fig. 2,
where a 51
current limit resistor is inserted in
series with CX. Note that a small pulse width de-
creasewill occour however, and RXmust beappro-
priately increased to obtain the originally desired
pulse width.
