9.5 555 Timer and Its Application
555 timer consist of comparators C1 and C2,
RS FF, open-collector transistor
RSFF set 0 T on
RSFF set 1 T off
If Vc1 and Vc2 low level outputs happen at
the different level of input signal, then input
and output show Schmitt trigger characteristic
if it has a period after Vc2 low level appearing
,Vc1 generate a low level output automatically,
we name it as Monostable multivibrator similarly
if Vc1 and Vc2 low level outputs appear
alternately, it
