Data Sheet
Truth Table
L = "Low" Level
H = "High" Level
Parallel switching of channel 1 and 2 is possible by connecting the inputs and outputs in parallel. The status
outputs ST1 and ST2 have to be configured as a 'Wired OR' function with a single pull-up resistor. The current
sense outputs IS1 and IS2 have to be connected with a single pull-down resistor.
