    Products Detail

    DS1678 Overview


    Among the packages 8-DIP (0.300, 7.62mm) is where real time clocks can be found.Basically, time clock is packaged in a way that is equivalent to Tube.This electrical RTC is powered by a voltage that is 4.5V~5.5V at the time of installation.The type of this electrical real time clock is Time Event Recorder.The position of this real time clock (RTC) on the system board is indicated by Through Hole.Temperatures should be kept at -40°C~85°C at all times for safe operation.When running a program, electronic time clocks may be possible to ensure that Alarm, Leap Year, NVSRAM, Y2K are maintained at all times.In the case of 8 terminations, transmission lines have the characteristic impedance of the terminating RTC module.A voltage of 5V is applied to this electronic component.As it has 8 pins, it is equipped with the necessary features.A crucial thing to remember is that this electrical digital time clock has a supply voltage of 2.6V~3.5V.The RTC times within the system have a memory of 32B available for storing data and programs for the purposes of the system.A frequency of 0.032MHz should not be exceeded by real time clocks' output frequency.
