NOTES FOR ELECTRICAL/SWITCHING CHARACTERISTICS

Note 1: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device

ground unless otherwise specified.

Note 3: Supply current specification is valid for loaded transmitters when DE = 0V.

Note 4: Applies to peak current. See

Typical Operating Characteristics.

Note 5: The MAX481E/MAX483E/MAX487E are put into shutdown by bringing

high and DE low. If the inputs are in this state for

less than 50ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are

guaranteed to have entered shutdown. See

Low-Power Shutdown Mode section.
