DS1391U-18+ Overview
In the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package, real time clocks is embedded.Tube is the way time clock is packaged.1.71V~1.89V is the supply voltage of this electrical RTC.Clock/Calendar is the type of this electrical real time clock.There is an real time clock (RTC) mounted in the way of Surface Mount.-40°C~85°C should be the operating temperature.Operating with Alarm, Leap Year, Square Wave Output, Trickle-Charger are possible.In 10 terminations, a transmission line is terminated with an impedance-matched RTC module.1.8V voltage is present on this electronic component.With 10 pins, it is equipped.The DS1391 family contains RTCs .This electrical digital time clock has a supply voltage of 1.3V~3.7V.The output frequency should not exceed 0.032MHz.Mounting type is Surface Mount.There are 10 pins on it.An input signal is received by 1 timers, which output a signal after a preset time.High efficiency requires a 1.8V supply voltage.
