The 555 timer datasheet specifies that 555 IC is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In ...
Whenever I use the 555 timer, it seems that the output polarity is invariably incorrect, and the way the 555 functions, it normally cannot generate a duty cycle of less than 50% — 90% yes, 10% NO!
