DS1678ST Product Details

DS1678ST Overview


It is possible to terminate a transmission line with a RTC module that matches the characteristic impedance of the line, which is known as 8 termination.Obviously, a voltage of 5V is being supplied to this electronic component.There are 8 pins on it.Real time clocks' output frequency should not exceed 0.032MHz.There are 5V power supplies attached to it.There is a maximum supply voltage (Vsup) of 5.5V.This electrical real time analog clock has the type TIMER, REAL TIME CLOCK of uPs/uCs/Peripheral ICs.For normal operation, the supply voltage (Vsup) should be kept above 4.5V.Operating temperatures should be below 85°C.
