4. During turn-on, the device requires an initial “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 can provide a minimum of 100 mA “Turn-on

Current”.

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

signal is applied prior to power supply.
