                                                PCF8584T/2,512 Overview
It can be found in the 20-SOIC (0.295, 7.50mm Width) package that you can download. This packaging has a Tube-shape, making it convenient to carry around. A temperature regulation of -40°C~85°C is necessary to ensure reliable operation. Using a 4.5V~5.5VV power source should be fine. In it, there are terminations that end in 20. 5V supply voltage allows high efficiency. In the world of numbers, it is a member of the PCF8584 family. A device that runs at 12MHz frequency will have a clock that runs at that frequency. There is currently a supply of 1.5mA in the market. It is set to 5V for the power supply of the component.
