SN74HC04: i am planning to use NOT gate IC for a logic creation by shorting all input pin together.

Part Number: SN74HC04


I am planning to use NOT gate IC part number SN74HC04D for a logic creation by shorting all input pin together. So that i can give 8 nos of common signal either HIGH or LOW to next circuit.(I am considering 8 nos of output considering two similar IC in parallel since the i am not getting any NOT gate ic with 8 nos of input pins) In case i will go with this design what will be challenges i need to have to consider while designing.

Kindly check below attach image for understanding the signal flow. 

The signal going through NOT gate IC as input will be 5V HIGH to make gate driver RDYC pin LOW to configure the IC after configuration i will make input of NOT GATE ic LOW to make gate driver RDYC pins high(Gate driver HEALTHY).

  • Hi Sourabh Kumar,

    I don't see any problem with this. As a heads up, the part you mentioned (SN74HC04) is not an 8-channel NOT gate, it has only 6 channels. You may be thinking of CD74HC04 which is 8 channels and has very similar specs. Stay within the datasheet specifications, and you should be fine.

    Regards,
