A package named 24-SOIC (0.295, 7.50mm Width) 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 Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output.A transmission line can have a 24 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 24 pins.DS17285 is the family name of this object.This electrical digital time clock is powered by 2.5V~3.7V voltage.Programs and data can be stored in the 2KB memory embedded in the RTC times.There should not be a frequency higher than 0.032MHz in the output.There is a power supply of 5V used to power the real time clock.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.
