9. Each DS1345 has a built-in switch that disconnects the lithium source until the user first applies V
CC
.
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. This parameter is assured by component selection, process control, and
design. It is not measured directly during production testing.
10. All AC and DC electrical characteristics are valid over the full operating temperature range. For
commercial products, this range is 0
°
C to 70
°
C. For industrial products (IND), this range is -40
°
C to
+85
°
C.
11. In a power-down condition the voltage on any pin may not exceed the voltage on V
CC
.
12. t
WR1
and t
DH1
are measured from
WE
going high.
13. t
WR2
and t
DH2
are measured from
CE
going high.
14.
RST
and
BW
are open-drain outputs and cannot source current. External pullup resistors should be
connected to these pins for proper operation. Both pins will sink 10mA.
15. DS1345 modules are recognized by Underwriters Laboratory (U.L.
) under file E99151.
