5.12 Electrical Characteristics—3.3-V Supply

VCC1 = VCC2 = 3.3 V ±10% (over recommended operating conditions unless otherwise noted)
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
VOH High-level output voltage IOH = -2mA VCCO - 0.3 (1) 3.2 V
VOL Low-level output voltage IOL = 2mA 0.1 0.3 V
VIT+(IN) Rising input switching threshold 0.6 x VCCI 0.7 x VCCI(1) V
VIT-(IN) Falling input switching threshold 0.3 x VCCI 0.4 x VCCI V
VI(HYS) Input threshold voltage hysteresis 0.1 x VCCI 0.2 x VCCI V
IIH High-level input current VIH = VCCI(1) at INx 10 µA
IIL Low-level input current VIL = 0V at INx -10 µA
CMTI(2) Common mode transient immunity VI = VCCI or 0V, VCM = 1200V 85 100 kV/μs
(1) VCCI = Input-side VCC; VCCO = Output-side VCC
(2) CMTI is measured only on digital isolator independent of transformer driver
