This parameter does not apply to the ISO1541 SCL1 line as it is uni-directional.
∆V
OIT1
= V
OL1
– V
IHT1
. This represents the minimum difference between a Low-Level Output Voltage and a High-Level Input Voltage
Threshold to prevent a permanent latch condition that would otherwise exist with bi-directional communication.
Any V
CC
voltages, on either side, less than the minimum will ensure device lockout. Both V
CC
voltages above the maximum will prevent
device lockout.
