DS1743-70+ Overview


Real time clocks is embedded in the 28-DIP Module (0.600, 15.24mm) package.There is a packaging method that is similar to Tube.4.5V~5.5V is the supply voltage of this electrical RTC.Clock/Calendar is the type of this electrical real time clock.There is an electronic component mounted in the way of Through Hole.Ideally, the operating temperature should be 0°C~70°C.During operation, Leap Year, NVSRAM, Y2K can be guaranteed.It is possible to terminate transmission lines with 28 terminations, which means that the RTC module terminating the line matches its characteristic impedance.Its supply voltage is 5V.There are 28 pins on it.RTCs are a member of the family DS1743.In Timer or RTC, this part is included.In the RTC times, there is a memory of 8KB that is available for storing programs as well as data.Real time clocks' output frequency should not exceed 0.032MHz.A total of 5V power supplies are required to operate it.
