Usually just the pin numbers are used and they are not labelled with their function. But if you don't, or you think the people reading the schematic won't, then you can draw some or all of the block diagram inside the part. The 556 is less popular and may cost more than two 555s so you may prefer to use two 555 timers. These on off intervals can be adjusted by varying the 555 timer output and number of counter outputs.
In monostable mode, the duration for which the pin 3 would remain high, is given by the below formulae:
