DS3803
9 of 10
3.
t
WP
is specified as the logical AND of
CE
and
WE
. t
WP
is measured from the latter of
CE
or
WE
going low to the earlier of
CE
or
WE
going high.
4.
t
DS
is measured from the earlier of
CE
or
WE
going high.
5.
These parameters are sampled with a 5 pF load and are not 100% tested.
6.
If the
CE
low transition occurs simultaneously with or later than the
WE
low transition, the output
buffers remain in a high impedance state during this period.
7.
If the
CE
high transition occurs prior to or simultaneously with the
WE
high transition, the output
buffers remain in a high impedance state during this period.
8.
If
WE
is low or the
WE
low transition occurs prior to or simultaneously with the
CE
low transition,
the output buffers remain in a high impedance state during this period.
9.
Each DS3803 has a built-in switch that disconnects the lithium source until V
CC
is first applied by the
user. The expected t
DR
is defined as accumulative time in the absence of V
CC
starting from the time
power is first applied by the user.
10.
In a power-down condition the voltage on any pin may not exceed the voltage on V
CC
.
11.
t
WR1
, t
DH1
are measured from
WE
going high.
12.
t
WR2
, t
DH2
are measured from
CE
going high.
