3. The 16 dB bit is connected to two driver input pins, so ΔIcc

needs to be calculated based on 6 TTL inputs.

4. Exceeding any one or combination of these limits may cause

permanent damage to this device.

5. M/A-COM does not recommend sustained operation near

these survivability limits.

6. Standard CMOS TTL interface, latch-up will occur if logic

signal is applied prior to power supply.
