DS1744-70+ Product Details
DS1744-70+ Overview
There is an embedded version in the package 28-DIP Module (0.600, 15.24mm).Packaged as Tube.This electrical RTC is powered by 4.5V~5.5V voltage.This electrical real time clock is of type Clock/Calendar.Through Hole is the way to mount this real time clock (RTC).A temperature of 0°C~70°C should be used for operation.During operation, Leap Year, NVSRAM, Y2K can be guaranteed.The 28 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.28 pins are attached to it.RTCs are a member of the family DS1744.In these RTC times, there is a memory of 32KB where data and programs can be stored.There should be no more than 0.032MHz frequency in real time clocks' output.A power supply of 5V is used to power it.28 pins are present on it.
