capacitive isolation between I/O lines. When one or
both I/O lines are at a logic-low level, the gate-control
logic turns the pass-FET on. When the pass-FET is
active, I/O V
the logic-low signal to be expressed simultaneously on
both I/O lines.
The MAX3394E/MAX3395E/MAX3396E have internal
10kΩ (typ) pullup resistors from I/O V
to the respective supply voltages, allowing operation
with open-drain drivers. Internal slew-rate enhancement
circuitry accelerates logic-state transitions, maintaining
a fast data rate with a higher bus load capacitance.
Additionally, the 10mA current sink drivers permit the
use of smaller external pullup resistors.
