DS1221S Product Details

DS1221S Overview


The package contains materials from Tube. The 16-SOIC (0.295, 7.50mm Width) is provided in order to conserve board space. This is a high quality and reliable type of Nonvolatile RAM. It is recommended that the operating temperature be set at 0°C~70°C. It is necessary to supply voltage to 4.5V~5.5V in order to ensure normal operation. Based on the technique of Surface Mount, it is mounted. The base part number DS1221 can be used to find more electronic parts related to this part. In order to prevent signals from reflecting off the end of the transmission line, 16 terminations are used. There is a supply voltage of 5V for the device. The 16 pins are configured on the board. This item belongs to the Power Management Circuits subcategory. In order to ensure the transmission of data, there are 1 channels. If the power supply of 5V is provided, high efficiency can be achieved. A maximum current of 80mA can be supplied without degrading the characteristics of the circuit or damaging it.
