'[EE]:555 Timer Controll Voltage Question?'
I have a 555 timer design that doesn't use the Control Voltage pin on
What is the proper termination if this pin is not used, can it be left
floating or should
I tie it to Vcc or Gnd?

Either let it float *OR* connect a small capacitor (0.01 uF) between pin 5
and Gnd. Don't connect it directly to either Vcc or Gnd.
