DS1251YP-70+ Overview
Packaged as Tray.The 34 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.It is possible to see 5V voltage being supplied to this RTC real time clock.34 pins are attached to it.A power supply of 5V is used to power it.When Vsup reaches 5.5V, the maximum supply voltage is reached.In this electrical real time analog clock, there is a uPs/uCs/Peripheral ICs type of TIMER, REAL TIME CLOCK.In order to operate normally, Vsup must remain above 4.5V.USE DS9034PCX TO ORDER POWERCAP are other characteristics of it.Below 70°C is the ideal operating temperature.
