Description
Receiver Output. When RE is low and A - B
When RE is low and A - B
Receiver Output Enable. Take RE low to enable RO; RO is high impedance when RE is high.
Take RE high and DE low to enter low-power shutdown mode.
Driver Output Enable. Take DE high to enable driver outputs. These outputs are high
impedance when DE is low. Take RE high and DE low to enter low-power shutdown mode.
Driver Input. With DE high, a low on DI forces non-inverting output low and inverting output
high. Similarly, a high on DI forces non-inverting output high and inverting output low.
