_______________________________________________________________________________________
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 VCC1 and VCC2 when shutdown is enabled.
Note 4: Limit guaranteed by applying 1520VRMS 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).
SWITCHING CHARACTERISTICS—MAX1480EA/MAX1490EA (continued)
(VCC_ = +5V ±10%, VFS = VCC_, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VCC_ = +5V and TA = +25°C.)
