Output Oscillates Normal Freq. Output Oscillates Normal High 'Z' state Stops Very low High 'Z' state Oscillates Lower than normal Delayed Immediate PACKAGING OPTIONS * When Pin 1 is allowed to float it is held 'high' by an internal pull-up resistor. Option 'N' = Pin 1 not connected internally. High temperature oscillators are available either tray packed (<250pcs) or tape and reel (>250 pieces). 16mm tape, 178mm or 330mm reels (EIA 418).
