... ODW DATA RETENTION MODE The DS1245AB provides full functional capability for V 4.5 volts. The DS1245Y provides full functional capability for V protects by 4.25 volts. Data is maintained in the absence of V The nonvolatile static RAMs constantly monitor V automatically write-protect themselves, all inputs become “don’t care,” and all outputs become high impedance ...
