DS1340Z-18 Overview
A package named 8-SOIC (0.154, 3.90mm Width) contains real time clocks.Tube is the packaging method.There is 1.71V~5.5V supply voltage for this electrical RTC.Electrical real time clocks of this type are Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Surface Mount.-40°C~85°C is the operating temperature.When operating, you can ensure Leap Year, Trickle-Charger.A transmission line can have a 8 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 1.8V voltage supplied to it.The RTCs are equipped with 8 pins.This electrical digital time clock is powered by 1.3V~3.7V voltage.There should not be a frequency higher than 0.032MHz in the output.
