[SI-LIST] Crowbar current in push-pull drivers

Does anybody have a feel for how much crowbar current 
(aka shoot-thru current) one should expect to see from a 
"well-behaved" HSTL-Class-1 or SSTL-18 driver? I am seeing 
43ma and 23ma transients (respectively, per driver) on the 
I/O supply when my drivers are switching.  These transients 
are two hundred to three hundred picoseconds in duration.  
Are these switching transients typical?
