is it fine to have floating pin with NE555 set for VCO
LaserTazerPhaser:
Would the floating discharge terminal cause damage to this oscillator?
T3sl4co1l:
No, it's an open collector.

It can be completely open.

It could be directly shorted to GND on your schem, (but not V+) with no effect, because discharging any cap to GND is what DIS does.

You may also connect it to VCC with no effect if you put an LED and series resistor in between :popcorn:
Or leave it floating because it really doesn't matter :)
