- This is the most direct way to test / reset the output.

- If raising p9 (reset) does not lower Q to logic "0"=<20% Vdd) replace the IC.
- No sweat, be more careful next time for handling failures of ESD etc. Most new IC failures are handling issues or over voltage on power-up which causes excess junction heat from shoot-thru Pch to Nch both ON at the same time.
