DS1744W-120IND+ Overview
28-DIP Module (0.600, 15.24mm) is where you'll find real time clocks.There is a way to package time clock in the form of a Tube.2.97V~3.63V is the supply voltage of this electrical RTC.This electrical real time clock has the type Clock/Calendar.On the system board, this real time clock (RTC) is mounted in Through Hole.Ideally, the operating temperature should be -40°C~85°C.Operating with Leap Year, NVSRAM, Y2K are possible.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.There is 3.3V voltage supplied to this RTC real time clock.As it has 28 pins, it is equipped with the necessary features.DS1744 are the family name of RTCs .In the subcategory of Timer or RTC, the RTCs can be found.For storing the programs and data, the RTC times have an embedded memory of 32KB for storing data and programs.In order for it to work properly, real time clocks' output frequency should not exceed 0.032MHz.The power supply is 3.3V.The real time clock is equipped with 28 pins.
