Block diagram from a CMOS 555 timer variant: The article describes the discharge pin as "in phase with the output," whatever that means. If you take that to mean that the discharge pin is shorted to ground whenever the output is LOW, then putting the 555 in reset should ground the discharge pin. 555 NE555 load resistor? Electrical Engineering Stack ... If you are driving a CMOS IC you do not need anything else connected to the OUT pin. The 555 has a "push pull" or bipolar output stage. This means that it drives "actively" both high and low, so you get an output voltage whether there is a load connected or not. The 555 load is generally connected to the OUT pin when you want a square wave output. AN170 NE555 and NE556 applications 555 Timer Circuits The simplicity of the timer, in conjunction with its ability to produce long time delays in a variety of applications, has lured many designers from mechanical timers, op amps, and various discrete circuits into the ever increasing ranks of timer users.
