Proper ESD control Operating Temperature -40C to +85C techniques should be used when handling these Storage Temperature -65C to +125C devices. 3. Exceeding any one or combination of these limits may cause permanent damage to this device. 4. MACOM does not recommend sustained operation near these survivability limits. 5. Standard CMOS TTL interface, latch-up will occur if logic signal is applied prior to power supply. 22 2 M/A-COM Technology Solutions Inc.
