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 DS1270 has a built-in switch that disconnects the lithium source until the user first applies VCC.
The expected tDR is defined as accumulative time in the absence of VCC 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 VCC.
12. tWR1 and tDH1 are measured from WE going high.
13. tWR2 and tDH2 are measured from CE going high.
14. DS1270 modules are recognized by Underwriters Laboratory (U.L.
) under file E99151.
