Editing 555 timer IC (section)

=== Name ===
Several books report the name "555" timer IC derived from the three 5 kΩ resistors inside the chip.<ref>{{Cite book|last1=Scherz|first1=Paul|url=https://books.google.com/books?id=lhSCCwAAQBAJ|title=Practical Electronics for Inventors |edition=4th |last2=Monk|first2=Simon|date=2016 |publisher=McGraw Hill |isbn=978-1-259-58755-9|pages=687|quote=The 555 gets its name from the three 5-kW +VCC R1 discharging path 555 R 2 C 6 resistors shown in the block diagram.
