DS1744W-120IND+ Product Details
DS1744W-120IND+ Overview
Real time clocks is embedded in the 28-DIP Module (0.600, 15.24mm) package.Time clock is packaged in the way of Tube.The supply voltage of this electrical RTC is 2.97V~3.63V.The type of this electrical real time clock is Clock/Calendar.This real time clock (RTC) is mounted in the way of Through Hole.The operating temperature should be -40°C~85°C.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.The supply voltage of this RTC real time clock is 3.3V.It is equipped with 28 pins.RTCs belongs to DS1744 family.The RTC times embed a memory of 32KB available for storing programs and data.Real time clocks' output frequency should not exceed 0.032MHz.It operates from 3.3V power supplies.There are 28 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock.
