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:

.SUBCKT LOGIC_FUNCTION_2_HC_2i_XOR_PP_ST_SN74HCS86 A B OUT VCC VEE
.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.

SN74HCS00.cir SN74HCS00_Behavioral_Model_v181105.TSC

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

********************************************************************************
* SN74HCS00.cir
* 1.0

* 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.

Thanks!
