Proper ESD control techniques should be used when handling these devices. Operating Temperature Storage Temperature 3. Exceeding any one or combination of these limits may cause permanent damage to this device. 4. M/A-COM 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. 2 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 is considering for development.
