PCF8885T/1,518 Overview
Packages are made with materials from Tape & Reel (TR). Surface Mount is needed to mount it on the PCB. 28-SOIC (0.295, 7.50mm Width) is extremely popular in the electronic industry due to its low package cost. Providing the 2.5V~5.5V Supply Voltage ensures the device's normal operation. There are inputs of 8. In standard grade applications, it is classified as Type Buttons. You should keep it at -40°C~85°C at all times when it is operational. The current supply for this system is provided by 10μA. In addition to the 28 pin, there are some other uses as well.
