SN74HCS00: SPICE Behavioral Model

Part Number: SN74HCS00
Other Parts Discussed in Thread: SN74HCS86,

I see that there is a SPICE behavioral model for the SN74HCS86.  This has been very useful in TINA/P-SPICE simulation.

Would it be possible to get a similar model for the SN74HCS00 NAND package?

Thanks, Best, Steve

  • OK, so looking into the SPICE Deck, it looks like you all had envisioned this.... I see provisions for the other functions:

    .PARAM AND = 0
    .PARAM NAND = 0
    .PARAM OR = 0
    .PARAM NOR = 0
    .PARAM XOR = 1
    .PARAM XNOR = 0

    It's a bit more complicated that just changing one of the parameters above it seems, though.  

  • Hi,

    Yes you are correct. We have made our models so that we can create the different functions quickly within the same family.

    Here is the HCS00 model.




  • Thanks.  It appears these models were completed some time ago:

    * SN74HCS00.cir
    * 1.0
    * 2019-09-13 00:00:00
    * Texas Instruments Incorporated.
    * Standard Logic, SLHR
    * 12500 TI Blvd
    * Dallas, TX -75243

    If they are already done, I would suggest please going ahead and adding them to the website/product folder.

    It's very  handy for mixed signal simulation in TINA/PSPICE, and the input hysteresis of these new HCS parts comes in quite handy.
