DS1340U-18+ Product Details

DS1340U-18+ Overview


The package 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) contains real time clocks.The package is in the form of Tube.This electrical RTC has a supply voltage of 1.71V~5.5V.This electrical real time clock has the type Clock/Calendar.Surface Mount is the way this real time clock (RTC) is mounted.Electronic time clocks are recommended that the operating temperature be -40°C~85°C.When operating, Leap Year, Trickle-Charger 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 8 termination.Obviously, a voltage of 1.8V is being supplied to this electronic component.There are 8 pins on it.The family RTCs belongs to are DS1340.This electrical digital time clock has a 1.3V~3.7V supply voltage.Real time clocks' output frequency should not exceed 0.032MHz.Surface Mount is the mounting type of the RTC module.It is equipped with 8 pins.In order to achieve high efficiency, the supply voltage should be kept at 1.8V.
