DS1642-70 Overview
This real time analog clock can be found in package 24-DIP Module (0.600, 15.24mm).Time clock is packaged in the manner of Tube.Electrical RTCs such as this have a 4.5V~5.5V supply.This electrical real time clock has the type Clock/Calendar.Here, Through Hole represents how this part is mounted.Ideally, the operating temperature should be set to 0°C~70°C.When operating, Leap Year, NVSRAM can be ensured.A transmission line with 24 terminations possesses the characteristic impedance of the RTC module terminating it.It is possible to see 5V voltage being supplied to this RTC real time clock.The DS1642 family contains RTCs .There is a component of this type in Timer or RTC.There is a memory size of 2KB available for storing data and programs on the real time analog clocks.There should be no frequency greater than 0.032MHz in real time clocks' output.The RTC module is mounted with mounting type Through Hole.There is a power supply of 5V used to power the real time clock.A total of 24 pins are equipped with the real time clock.Maintaining the supply voltage at 5V is the key to high efficiency.
