Oscillator IC data

This is a collection of data about using gates for oscillators. I'm just posting them for reference. The main point is the unbuffered inverter is what TI recommends. If you use more than one inverter (or a buffered inverter) it becomes impossible to control the phase shift as the feedback will 'self adjust'.

TI's App Note specifies unbuffered. Most references on the net seen to leave that part off.
