_______________________________________________________________________________________
Note 1:
All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to logic-
side ground (GND_), unless otherwise specified.
Note 2:
For DE

and DI

pin descriptions, see
Detailed Block Diagram and Typical Application Circuit
(Figure 1 for MAX1480EA/
MAX1480EC, Figure 2 for MAX1490EA/MAX1490EB).
Note 3:
Shutdown supply current is the current at V
CC1
and V
CC2
when shutdown is enabled.
Note 4:
Limit guaranteed by applying 1520V
RMS
for 1s. Test voltage is applied between all pins on one side of the package to all
pins on the other side of the package, e.g., between pins 1–14 and pins 15–28 on the 28-pin package.
Note 5:
Applies to peak current (see
Typical Operating Characteristics
). Although the MAX1480EA/MAX1480EC and
MAX1490EA/MAX1490EB provide electrical isolation between logic ground and signal paths, they do not provide isolation
between external shields and the signal paths (see
Isolated Common Connection
section).
