8.2 DefiningaComplexDevice
In this section we use the example of a TTL chip (541032) to define a li
-
brary element that is to be used in two different packages (pin-leaded
and SMD). It is a quad OR gate. The schematic diagram symbol is to be
defined in such a way that the individual OR gates can be placed one af
-
ter another. The power supply pins are not initially visible in the sche
-
maticdiagram,butcanbefetchedintothediagramifneeded.
