DS1743-70+ Product Details
DS1743-70+ 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 4.5V~5.5V.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 5V is being supplied to this electronic component.There are 28 pins on it.The family RTCs belongs to are DS1743.For storing data and programs, the RTC times embed a memory of 8KB.Real time clocks' output frequency should not exceed 0.032MHz.There are 5V power supplies attached to it.
