Electrical Characteristics

VBIAS(VDD, VBS)=15.0V, VSS=COM=0V, DT=VSS and TA = 25°C, unless otherwise specified. The VIN and IIN

parameters are referenced to VSS/COM and are applicable to the respective input leads: IN and SD. The VO and IO

parameters are referenced to COM and are applicable to the respective output leads: HO and LO.

Note:

5

These parameters guaranteed by design.
