ANALOG multiplexer

Hello,

I'm trying to use ADG436BNZ analog switch for my application, I downloaded the library but is no Pspice model for it, then i tried to use CD4016B form TI, I entered on their site to find the Pspice model  but is no model aswell. In my application I need to switch between two analog signals considering a signal from a D flil-flop. Can i get from you guys a switch that  has a Pspice model?

Thanks!
