_______________________________________________________________________________________

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 (GND1, GND2), unless otherwise specified.

Note 2: For DE

MAX3480EA/MAX3480EB).

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. For example, between pins 1 and 14, and 15 and 28.

Note 5: Applies to peak current. See Typical Operating Characteristics and Applications Information.
