In failure(instantaneous drop)
Input voltage:5V
With Q4 set to ON,
a voltage

)is output
The output level is
V
OL
(RES)
with a logic low
The output level is

with a logic low
The output level is
V
OL
(CS)
with a logic low
Input voltage:5V 4V
Each output varies if the input
voltage drops to V
SL
or under
Q4 is turned OFF.A voltage
(VIN-Q4 VEB(Di) is output by
the diode between E and B of
Q4
As the state shifts from a logic
low to logic high,the output level
becomes approximately equal to
the input voltage
As the state shifts from a logic
high to logic low,the output level
becomes V
OL
(RES)
As the state shifts from a logic
low to logic high,the output level
becomes the voltage V

Restoration from failure
(instantaneous drop)
Input voltage:4V 5V
If the input voltage goes higher
than VSL by 100mV,each out-put
varies after delay produced by the
delay circuit
Q4 is turned ON after delay and
a voltage(V
IN
-V
DROP
) is output
A logic high is maintained,and than
shifts to a logic high
A logic low is held,and than shifts
to a logic high
A logic high is maintained,and than
shifts to a logic high

Input voltage:0V
Backup voltage:3V
