*RST and *TST (important!)
The *RST and power-on condition (true also after *TST) for output- configured channels will output a logical one (open-drain output off). You should keep this behavior in mind when applying the E1415 to your system. It is best to have your system’s digital inputs use a high (one) as their safe state.
