DS14285QN+ Overview
This real time analog clock can be found in package 28-LCC (J-Lead).The package is packaged in the way of Tube.Its supply voltage is 4.5V~5.5V.This electrical real time clock has the type Clock/Calendar.This real time clock (RTC) is mounted in the way of Surface Mount.The temperature should always be kept at -40°C~85°C to ensure safe operation.When operating, Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output can be ensured.There is the possibility of terminating transmission lines with 28 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.In this case, the voltage supplied to the electronic component is 5V.It is equipped with the necessary features since it has 28 pins.DS14285 is the family name of this object.It is important to keep in mind that the supply voltage of this electrical digital time clock is 2.5V~3.6V.There is a component of this type in Timer or RTC.A memory of 114B is embedded in the RTC times, which can be used to store programs and data.A frequency of 0.032MHz should not be exceeded by real time clocks' output frequency.For the purpose of powering the real time clock, the power supply is set to 5V.When an input signal is received, 1 timers are used to output a signal at a preset time.
