ENABLE VS. TRI-STATE
Enable: When pin 19,20 is low (0), the oscillator stops oscillation. Tri-state: When pin 19,20 is low, the oscillator is running. However, the output buffer amplifier stops functioning and output is in high impedance (Z) state. Enable Current consumption when pin 19,20 is low Output recovery delay when pin 19,20 changes from low (0) to high (1) Low Delayed Tri-state High Immediate
1. Tighter tolerances available for calibration, stability and duty cycle. 2. Does not include calibration tolerance. 3. High shock version available. 4. Consult factory for operating temperatures above 125OC. Note: All parameters are measured at ambient temperature with a 10M and 15pF load at 5V
