-5mA ≤ IDIFFSENS ≤ 50µA
VDIFFSENS = 0V
VDIFFSENS = 2.75V
With ISO high, |VDIFFSENS| = 0.3V
With ISO high, |VDIFFSENS - VTPWR| = 0.3V
For increasing temperature
VCC = 3.3V
VCC = 3.3V, VLOAD = 2.4V
VCC = 3.3V, VLOAD = 0.4V
VIL = -0.3V
Note 1: All voltages are referenced to ground.
Note 2: Guaranteed by design and not production tested.
Note 3: Room temperature only.
