NOT gate simulation

Hi,

I'm trying to simulate a NOT gate 74LS04 (DC sweep) in order to see the analog output voltage but I guess that a complete analog model is not included in the library. Then I decided to download the Pspice model available from Texas Instruments (Spice model option):

https://www.ti.com/product/SN74LS04#design-development##design-tools-sim...

I convert the file to .olb following this video https://www.youtube.com/watch?v=oQoYadfy5MI​ 

everything seems ok but simulation is not working

* source NOT_TI
V_V1         N00075 0 5Vdc
R_R1         0 N00400  1meg TC=0,0 
V_V2         N00234 0 0Vdc
X_U1         N00400 N00234 N00075 0 SN74LS04 

**** RESUMING 1.cir ****
.END

ERROR(ORPSIM-15108): Subcircuit SN74LS04 used by X_U1 is undefined

 

Any idea about how to fix that?
