DS1685QN-3 Product Details
DS1685QN-3 Overview
A package named 28-LCC (J-Lead) contains real time clocks.Tube is the packaging method.There is 2.7V~3.7V 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 Alarm, NVSRAM, Square Wave Output, Y2K.A transmission line can have a 28 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 3V voltage supplied to it.The RTCs are equipped with 28 pins.This electrical digital time clock is powered by 2.5V~3.7V voltage.Programs and data can be stored in the 242B memory embedded in the RTC times.There should not be a frequency higher than 0.032MHz in the output.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.
