NAME
FUNCTION
1
鈥�
SHDN
Shutdown. Drive SHDN high to enter low-power shutdown mode.
22
1
RO
Receiver Output. When RE is low and (A - B)
鈮� -50mV, RO is high; if (A - B) 鈮�
-200mV, RO is low.
3鈥�
2
RE
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.
4鈥�
3
DE
Driver Output Enable. Drive DE high to enable driver output. The driver
outputs are high impedance when DE is low. Drive RE high and DE low to
enter low-power shutdown mode. Do not leave RE unconnected when using
the MAX3466 or MAX3469.
53
4
DI
Driver Input. With DE high, a low on DI forces the noninverting output low and
the inverting output high. Similarly, a high on DI forces the noninverting output
high and the inverting output low.

GND
Ground
8
鈥�
TXP
Transmitter Phase. Connect TXP to GND, or leave unconnected for normal
transmitter phase/polarity. Connect TXP to VCC to invert the transmitter
phase/polarity. TXP has an internal 15A pulldown.
