We use an SN74LVC14APWR as FAN PWM control circuit, we do not add the current limitation resistor between 74lvc14 output to transistor (V9). And the output of SN74LVC14APWR will be fixed to about 1V,could you help let your R&D evaluate the risk of this application? And could you share the internal block circuit of SN74LVC14APWR for review?
