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.

DC ELECTRICAL CHARACTERISTICS

(VCC = +4.75V to +5.25V, no RF signals applied, all input and output ports terminated with 50Ω, TA = -40°C to +85°C, unless other-

wise noted. Typical values are at VCC = +5.0V, TA = +25°C, unless otherwise noted.)
