possible to turn all the ICs on or off at the same time remotely.
Application Notes (continued)
Multiple instances of this IC can be operated in parallel. If the OSC pins (pin 15) and Off pins (pin 6) are connected
It is also possible to operate a one-channel control IC (e.g. the AN8016SH or AN8016NSH) and a two-channel
Note that it is not possible to control the on/off states of each IC operating in this mode independently. It is only
