The transistor in the circuit diagram is a light blue background, always energized when the output is low level. Deutsch: Der NE555 enthält 24 Bipolartransistoren, zwei Dioden und 15 Widerstände, die zusammen sechs Funktionsblöcke bilden:
In 1972, Signetics originally released the 555 timer in DIP-8 and TO5-8 metal can packages, and the 556 timer was released in a DIP-14 package. [ 4 ] In 2006, the dual 556 timer was available in through-hole packages as DIP-14 (2.54 mm pitch), [ 21 ] and surface-mount packages as SO-14 (1.27 mm pitch) and SSOP-14 (0.65 mm pitch).
