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 DS1265 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. DS1265 modules are recognized by Underwriters Laboratory (U.L.Ò) under file E99151.
