DS1344E-33+ Product Details

DS1344E-33+ Overview


Real time clocks is embedded in the 20-TSSOP (0.173, 4.40mm Width) package.Time clock is packaged in the way of Tube.The supply voltage of this electrical RTC is 3V~5.5V.The type of this electrical real time clock is Clock/Calendar.This real time clock (RTC) is mounted in the way of Surface Mount.The operating temperature should be -40°C~85°C.Alarm, Leap Year, NVRAM, Square Wave Output, Trickle Charger can be ensured when operating.There are 20 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.The supply voltage of this RTC real time clock is 3.3V.It is equipped with 20 pins.RTCs belongs to DS1344 family.The supply voltage of this electrical digital time clock is 1.3V~5.5V.The RTC times embed a memory of 96B available for storing programs and data.Real time clocks' output frequency should not exceed 4MHz.It is mounted in the way of Surface Mount.There are 20 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.The supply voltage should be maintained at 3.3V for high efficiency.
