NAME FUNCTION
1, 8, 13 — — — — N.C.
No Connect. Not internally connected, can be connected
to GND.
———11H/F
Half-/Full-Duplex Select Input. Connect H/F to V
CC
for
half-duplex mode; connect H/F to GND or leave
unconnected for full-duplex mode.
22122RO
Receiver Output. When RE is low and if (A - B) ≥ -50mV,
RO is high; if (A - B) ≤ -200mV, RO is low.
3—233RE
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).
4—344DE
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).

— — — 6 6 SRL
Slew-Rate Limit Selector Input. Connect SRL to ground for
16Mbps communication rate; connect SRL to V
CC
for
500kbps communication rate. Leave SRL unconnected for
250kbps communication rate.
