Note:  The following SPICE model is for the individual elements of this device.
When applying this SPICE model to your circuit simulation be certain to 
add R1 and R2 values per the table found on the data sheet for the pre-biased
transistor elements. 
Allow +/- 30% resistance tolerance and +/- 20% for R2/R1 ratio tolerance.
