SN55LVDS31: SN55LVDS31 and SN55:VDS332 SPICE models

Part Number: SN55LVDS31

Tool/software:

Hi Team,

I need a SPICE model for the SN55LVDS31 and SN5LVDS31 circuits.  I know they supply IBIS models but for what I am trying to model I need to know what is going on with the chip at the transistor level.  If this is impossible I would like the SPICE parameters for the transistors used in the chip so I can create my own model.

Cheers,

Anders
