Auto-Power-Down

Auto-Power-Down can be used to automatically save power when the receivers are unconnected or connected to a powered down remote RS232 port. FORCEON being high will override Auto power down and the drivers will be active. FORCEOFF being low will override FORCEON and will power down all outputs except for ROUT2B and INVALID.
