DS1250W
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 DS1250W 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 W E going high.
13. t WR2 and t DH2 are measured from CE going high.
14. DS1250 modules are recognized by Underwriters Laboratories (UL) under file E99151.
