DS1345Y/AB
9 of 12
9. Each DS1345Y has a built-in switch that disconnects the lithium source until VCC is first applied by
the user. The expected tDR is defined as accumulative time in the absence of VCC 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 VCC.
12. tWR1 and tDH1 are measured from WE going high.
13. tWR2 and tDH2 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.
