DS1345W
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 W E 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.
