Proper ESD control techniques should be used when handling these devices. 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.
