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. M/A-COM does not recommend sustained operation near
these survivability limits.
8. Standard CMOS TTL interface, latch-up will occur if logic sig-
2
nal is applied prior to power supply.
