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.
9. Application Note S2083 is available on line at www.macom.com.
