DS1340U-3+ Product Details

DS1340U-3+ Overview


There is an embedded version in the package 8-TSSOP, 8-MSOP (0.118, 3.00mm Width).Packaged as Tube.This electrical RTC is powered by 2.7V~5.5V voltage.This electrical real time clock is of type Clock/Calendar.Surface Mount is the way to mount this real time clock (RTC).A temperature of -40°C~85°C should be used for operation.During operation, Leap Year, Trickle-Charger can be guaranteed.The 8 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.It is possible to see 3V voltage being supplied to this RTC real time clock.8 pins are attached to it.RTCs are a member of the family DS1340.Its supply voltage is 1.3V~3.7V.There should be no more than 0.032MHz frequency in real time clocks' output.This RTC module has a mounting type of Surface Mount.A power supply of 3V is used to power it.8 pins are present on it.RTC time is important to maintain the supply voltage at 3V in order to maintain high efficiency.
