DS1744W-120+ Product Details

DS1744W-120+ Overview


The package 28-DIP Module (0.600, 15.24mm) contains real time clocks.The package is in the form of Tube.This electrical RTC has a supply voltage of 2.97V~3.63V.This electrical real time clock has the type Clock/Calendar.Through Hole is the way this real time clock (RTC) is mounted.Electronic time clocks are recommended that the operating temperature be 0°C~70°C.When operating, Leap Year, NVSRAM, Y2K can be ensured.It is possible to terminate a transmission line with a RTC module that matches the characteristic impedance of the line, which is known as 28 termination.Obviously, a voltage of 3.3V is being supplied to this electronic component.There are 28 pins on it.The family RTCs belongs to are DS1744.For storing data and programs, the RTC times embed a memory of 32KB.Real time clocks' output frequency should not exceed 0.032MHz.There are 3.3V power supplies attached to it.It is equipped with 28 pins.
