Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
1. Guaranteed by design
2. CS pin source current is a sum of IBIAS and IOPP, thus at VHV = 125 V is observed the IBIAS only, because IOPC is switched off.
