I was making our project when I observed the designation of pins to the ICs specifically dual in line packages. I am wondering why for an 8 pin IC, pin 4 is gnd and pin 8 is VCC. For 16 pins, pin 8 is gnd and pin 16 is VCC. One thing more, pin 3 is the output as of an ne555 or the beginning of the output as in 4017. Is there any convention in designation of IC pins? Your answers will ease my curiosity. ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
