DS1747P-70 Product Details

DS1747P-70 Overview


A package named 34-PowerCap™ Module contains real time clocks.Tube is the packaging method.There is 4.5V~5.5V supply voltage for this electrical RTC.Electrical real time clocks of this type are Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Surface Mount.0°C~70°C is the operating temperature.When operating, you can ensure Leap Year, NVSRAM, Y2K.A transmission line can have a 34 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 5V voltage supplied to it.The RTCs are equipped with 34 pins.This electrical digital time clock is powered by 3V voltage.Programs and data can be stored in the 512KB memory embedded in the RTC times.There should not be a frequency higher than 0.032MHz in the output.There are also A POWERCAP MODULE CONTAINING CRYSTAL AND BATTERY REQUIRED characteristics.
