DS1744W-120 Overview
There is a package called 28-DIP Module (0.600, 15.24mm) which contains real time clocks, and you can find real time clocks there.Tube is the way in which time clock is packaged.In this electrical RTC, the supply voltage is 2.97V~3.63V.An electrical real time clock of type Clock/Calendar can be said to be this one.Through Hole indicates how this real time clock (RTC) is mounted.A temperature of 0°C~70°C should be used for operation.Leap Year, NVSRAM, Y2K can be ensured when operating.There are 28 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.RTC real time clocks like this have a 3.3V supply voltage.With 28 pins, it is equipped with the necessary functions.DS1744 are RTC s family.A part like this is included in Timer or RTC.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 32KB.The output frequency of this real time analog clock should not exceed 0.032MHz Hz.This RTC module is mounted using type Through Hole.There are 28 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. RTC time is essential that the supply voltage remain at 3.3V for maximum efficiency.
