VSC838-01
Datasheet
Unused channels may be powered down to allow efficient use of the switch in applications that require only a subset
of the channels. Power-down can be accomplished in hardware via dedicated power pins for pairs of input and output
channels, or in software by programming individual unused outputs with a disable code.
