nama pemasa 555 berasal daripada fakta bahawa terdapat tiga perintang 5kΩ disambungkan bersama-sama secara dalaman menghasilkan rangkaian pembahagi voltan antara voltan bekalan pada pin 8 dan tanah pada pin 1. voltan merentasi rangkaian perintang siri ini memegang input penyongsangan negatif pembanding dua pada 2/3vcc dan input bukan penyongsangan positif kepada pembanding satu pada 1/3vcc.
the 555 timers name comes from the fact that there are three 5kΩ resistors connected together internally producing a voltage divider network between the supply voltage at pin 8 and ground at pin 1. the voltage across this series resistive network holds the negative inverting input of comparator two at 2/3vcc and the positive non inverting input to comparator one at 1/3vcc.
