10)If channels are connected in parallel, output clamp is usually accomplished by the channel with the lowest

11)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. Note that the power dissipation is higher compared to normal
operating conditions due to the voltage drop across the intrinsic 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 3 and circuit page 8).

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.

Timing diagrams
Timing diagrams are shown for chip 1 (channel 1/2). For chip 2 (channel 3/4) the diagrams
are valid too. The channels 1 and 2, respectively 3 and 4, are symmetric and consequently
the diagrams are valid for each channel as well as for permuted channels
