NAND .model


 

Hi,

I'm having a problem with another program that use LTSpice to run the simulation. The schematic have a NAND gate, and I write a ".model" like the one below, but the LTSpice seems don't recognize the "d_nand" expression.

** 2 input NAND schmitt
.model A4093 d_nand ( in_family="4000-5_SCHMITT"
+ out_family="4000-5"
+ out_res=560
+ input_load=5p
+ rise_delay=162n
+ fall_delay=162n
+ max_source = 3.2m
+ min_sink = -1m )

Anyone know how can I solve this?

Best regards,
S.
