DS1743-85IND+ Product Details

DS1743-85IND+ Overview


Tube is the packaging method.A transmission line can have a 34 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 5V voltage supplied to it.The RTCs are equipped with 34 pins.Programs and data can be stored in the 8kB memory embedded in the RTC times.There should not be a frequency higher than 0.032MHz in the output.Mounting type for the RTC module is Through Hole.28 pins are attached to it.Optimal efficiency requires a supply voltage of 5V.A temperature above -40°C is recommended for operation.Lower than 85°C is the recommended operating temperature.Real time clocks operate with a voltage of 4.5V.There is 5.5V maximum supply voltage for real time clocks.

DS1743-85IND+ Features


34 terminations
34 pin count
Be maintained at 5V for high efficiency.
