DS1339BU+T Product Details

DS1339BU+T Overview


This real time analog clock can be found in package 8-TSSOP, 8-MSOP (0.118, 3.00mm Width).The package is packaged in the way of Tape & Reel (TR).Unless otherwise stated, this electrical RTC's supply voltage is 1.71V~5.5V.This electrical real time clock is type Clock/Calendar.This part is mounted on the systemboard in the way indicated by Surface Mount.Ideally, the operating temperature should be set to -40°C~85°C.Electronic time clocks are possible to make sure that Alarm, Leap Year, Square Wave Output, Trickle-Charger are maintained when operating.8 terminations are available for transmission lines, implying that the RTC module terminating the line matches its characteristic impedance.RTC real time clocks such as this one are powered by 3.3V voltage.As a member of the DS1339 family, RTCs belongs to them.A voltage of 1.3V~3.7V is required for the supply of this electrical digital time clock.There is a mounting type Surface Mount specified for the RTC module.A total of 1.8/5V power supplies are required to operate it.An input signal is received by 1 timers, which output a signal after a preset time.
