Inclusive of Hold Over stability, supply voltage change (±5%), aging, 24 hours 2. Inclusive of calibration @ 25°C frequency vs. change in temperature, change in supply voltage (±5%), load change (±5%), reflow soldering process and 20 years aging. 3. Leave Pad 8 unconnected if enable / disable function is not required. When tri-stated, the output stage is disabled but the oscillator and compensation circuit are still active (current consumption ≤ 1 mA).
