9.
Each DS1345Y 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.
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 10 mA.
DC TEST CONDITIONS
Outputs Open
Cycle = 200 ns for operating current
All voltages are referenced to ground
AC TEST CONDITIONS
Output Load: 100 pF + 1TTL Gate
Input Pulse Levels: 0 - 3.0V
Timing Measurement Reference Levels
Input: 1.5V
Output: 1.5V
Input pulse Rise and Fall Times: 5 ns
