Receiver Output
Receiver Output Enable. Drive RE low to enable RO. RO is high impedance when RE is high. Drive
RE high and DE low to enter low-power shutdown mode. RE is a hot-swap input (see the Hot-Swap
Capability section for more details).
Driver Output Enable. Drive DE high to enable the driver outputs. These outputs are high-impedance
when DE is low. Drive RE high and DE low to enter low-power shutdown mode. DE is a hot-swap input
(see the Hot-Swap Capability section for more details).
Driver Input. Drive DI low to force noninverting output low and inverting output high. Drive DI high to
force noninverting output high and inverting output low (see the Function Tables).
