not designed for continuous repetitive operation.

Requires a 150 Ω resistor in GND connection. The reverse load current through the intrinsic drain-source
diode has to be limited by the connected load. Power dissipation is higher compared to normal operating
conditions due to the voltage drop across the drain-source diode. The temperature protection is not active
during reverse current operation! Input and Status currents have to be limited (see max. ratings page 4 and
circuit page 9).

Parallel switching of channel 1 and 2 (also channel 3 and 4) is easily possible by connecting the inputs and
outputs in parallel (see truth table). If switching channel 1 to 4 in parallel, the status outputs ST1/2 and ST3/4
have to be configured as a 'Wired OR' function with a single pull-up resistor.
