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.

pin descriptions, see
Detailed Block Diagram and Typical Application Circuit
(Figure 1 for MAX1480A/
MAX1480B/MAX1480C, Figure 2 for MAX1490A/MAX1490B).
Note 3:
Shutdown supply current is the current at V
CC1
and V
CC2
when shutdown is enabled.
Note 4:
Applies to peak current (see
Typical Operating Characteristics
). Although the MAX1480A/B/C and MAX1490A/B 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).
