Short circuit protect and detection
external power active, output signal active, and output port
voltage less than 2V.
Open wire detect off-state leakage current 0.1 mA When external power active and output signal inactive.
Detect reverse polarity voltage
external power supply voltage is greater than the value.
Delay time is the time from the receipt of an output on or off command to the output actually turning on or off.
