VI = VS(1)(ISOW7821 with F suffix)		 17 mA
No external ILOAD; VI = VSI (ISOW7821);
VI = 0 V (ISOW7821 with F suffix)		 14
All channels switching with square wave clock input of 1 Mbps; CL = 15 pF, No external ILOAD 16
All channels switching with square wave clock input of 10 Mbps; CL = 15 pF, No external ILOAD 17
All channels switching with square wave clock input of 100 Mbps; CL = 15 pF, No external ILOAD 27
IISO(OUT)(2) Current available on isolated supply VI = 0 V (ISOW7821); VI = VSI (ISOW7821 with F suffix) 127 mA
VI = VSI (ISOW7821); VI = 0 V (ISOW7821 with F suffix) 130
