DS1744W-120+ Overview
In the 28-DIP Module (0.600, 15.24mm) package, real time clocks is embedded as a dependency.As you can see, time clock is packaged as if time clock were in the form of Tube.It is important to keep in mind that the supply voltage of this electrical RTC is 2.97V~3.63V.Electrical real time clock type Clock/Calendar.There is an electronic component mounted in the way of Through Hole.In order to be safe, electronic time clocks are imperative that the temperature are kept at 0°C~70°C at all times.When operating, electronic time clocks are possible to make sure that Leap Year, NVSRAM, Y2K remains constant in the process.There are 28 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.This RTC real time clock is powered by 3.3V volts.It is equipped with 28 pins.DS1744 is the family name of this object.Timer or RTC includes this component in its content.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 32KB.Ensure that the output frequency does not exceed 0.032MHz.A total of 3.3V power supplies are required to operate it.There are 28 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock.
