Note 2: Parameters are 100% production tested at +25°C, limits over temperature are guaranteed by design.

Note 3: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device

ground, unless otherwise noted.

Note 4: VCM is the common-mode input voltage. VID is the differential input voltage.

Note 5: Not production tested. Guaranteed by design.

Note 6: See Table 2 for MAX3284E data rates with VL < VCC.
