1. Typical values are at 25 °C and are for design aid only; not guaranteed and not subject to production testing.
2. Voltages with respect to ground unless otherwise specified.
3. Per port @ 3.3V.
4. Environmental Condition - Natural convection (still air). Topc should be measured in the worst case thermal condition
(chassis, application, environment). If the Topc is greater than 122C, Air Flow (‘100 LFM) or heat sink (Attach: Thermoset
WP100 tape, 1”x1” square with a 0.75” diameter phase-change dot. Heat Sink: Thermally 31x31 mm-sq low profile, P/N
22370B must be added. Alternate thermal solutions may be used and/or required depending on specific system conditions.
