Notes 6. When the output is “H”, the circuit current decreases by approximately 1 mA (when VCC = 5 V).
7. The maximum allowable value for RA + RB is determined for a supply voltage of 15 V. The maximum
value is 20 MΩ.
8. When the reset pin is driven to a low level, discharge TrQ14 is turned on, stopping oscillation (the output
state is undefined).
