(1) This parameter does not apply to the SCL1 line of the ISO1641 device because it is unidirectional.

(2) ∆V_OIT1 = V_OL1 – V_IHT1. This value represents the minimum difference between a threshold for the low-level output voltage and a threshold for the high-level input voltage to prevent a permanent latch condition that would otherwise occur with bidirectional communication.

(3) Any supply voltages on either side that are less than the minimum value make sure that the device does a lockout. Both supply voltages that are greater than the maximum value keep the device from a lockout.
