Input pin.
This pin is connected to a pull-down resistor internally, so that even when input wiring is
open-circuited, output can never be turned on inadvertently.
Output pin.
The current limit for output current is 5 A (typ.) when excessive current flow into a device because
of in-rush current and short load of a lamp.
