Half-/Full-Duplex Select Pin. Connect H/F to V
duplex mode; connect to GND or leave unconnected for
full-duplex mode.
Receiver Output. When RE is low and if (A - B)
RO is high; if (A - B)
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
details).
Driver Output Enable. Drive DE high to enable 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 details).
Driver Input. With DE high, a low on DI forces noninverting
output low and inverting output high. Similarly, a high on
DI forces noninverting output high and inverting output
low.
Slew-Rate Limit Selector Pin. Connect SRL to ground for
16Mbps communication rate; connect to V
500kbps communication rate. Leave unconnected for
250kbps communication rate.
Ground
Transmitter Phase. Connect TXP to ground or leave
unconnected for normal transmitter phase/polarity.
