Note 1: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
ground, unless otherwise noted.
Note 2: ΔV
OD
and ΔV
OC
are the changes in V
OD
and V
OC
, respectively, when the DI input changes state.
Note 3: The short-circuit output current applies to peak current just prior to foldback-current limiting; the short-circuit foldback output
current applies during current limiting to allow a recovery from bus contention.
Note 4: Capacitive load includes test probe and fixture capacitance.
Note 5: Shutdown is enabled by bringing RE high and DE low or by bringing SHDN high. If the enable inputs are in this state for less
than 50ns, the device is guaranteed not to enter shutdown. If the enable inputs are in this state for at least 800ns, the device
is guaranteed to have entered shutdown.

NAME FUNCTION
1 SHDN Shutdown. Drive SHDN high to enter low-power shutdown mode.
221RO
Receiver Output. When RE is low and (A - B) -50mV, RO is high; if (A - B)
-200mV, RO is low.
3—2RE
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—3DE
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.
534DI
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.
