Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. NZB b. Pulse test: PW v300 ms duty cycle v3%. c. Gain (Gpg) measured at optimum input noise match. d. Not a production test. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. |
