ELECTRICAL CHARACTERISTICS (continued)
(VBIAS (VDD, VBS) = 15 V, TA = −40°C to 125°C unless otherwise specified. The VIN and IIN parameters are referenced to VSS. The VO
and IO parameters are referenced to VS and COM and are applicable to the respective outputs HO and LO.)

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.
6. Parameter guaranteed by design.
7. The turn−on propagation delay does not includes the dead time.
8. The dead time includes the turn on propagation time.
