4. During turn-on, the device requires an initial start up current (Icc) specified as “Turn-on Current”. Once operational, Icc will drop to the
specified levels.
5. The DC-DC converter is guaranteed to start in 100 µs as long as the power supplies have the maximum turn-on current available for
start up.

6. Exceeding any one or combination of these limits may cause
permanent damage to this device.
7. MACOM does not recommend sustained operation near these
survivability limits.
8. Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
