NOTES:
High
1. Ramp voltage at Pin 7 Low
where t = OSC period in microseconds
t
t ≅ RTCT with CT in microfarads and RT in ohms.
Output frequency at each output transistor is half OSC frequency when each output is used separately and is equal to the OSC frequency
when each output is connected in parallel.
2. Excluding oscillator charging current, error and current limit dividers, and with outputs open.
