CELow to High Transition
Once the last data bit has been shifted into the
L9822NSP,the CE pin shouldbe pulledhigh.
Attherising edgeof CEthe shiftregisterdataislat-
chedintotheparallellatchandtheoutputstageswill
beactuatedbythe newdata.Aninternal160
μ
s de-
laytimer will also be startedat thisrisingedge (see
t
UD
). During the 160
μ
s period, the outputs will be
protectedonlybytheanalogcurrentlimiting circuits
since the resetting of the parallel latches by faults
conditionswillbeinhibitedduringthisperiod.Thisal-
lowsthe part to overcomeany high inrushcurrents
that may flow immediately after turn on. Once the
delay period has elapsed, the output voltages are
sensedbythecomparatorsandanyoutputwithvol-
tageshigherthan1.8VarelatchedOFF.Itshouldbe
notedthatthe SCLK pinshouldbe lowatbothtran-
sitions of the CE pin to avoidany false clocking of
theshiftregister.TheSCLKinputis gatedbytheCE
pin, so that the SCLK pin is ignored whenever the
CE pinis high.
FAULTCONDITIONSCHECK
Checkingforfaultconditionsmaybedoneinthefol-
lowing way. Clock in a new control byte. Wait 160
microseconds or so to allow the outputs to settle.
