2 / 12 page 315MHz Low-Power, +3V Superheterodyne Receiver 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS DC ELECTRICAL CHARACTERISTICS (Typical Application Circuit, VDD = +3.0V to +3.6V, no RF signal applied, TA = -40°C to +85°C. Typical values are at VDD = +3.3V, TA = +25°C, unless otherwise noted.) (Note 1) AC ELECTRICAL CHARACTERISTICS (Typical Application Circuit, all RF inputs and outputs are referenced to 50 Ω, VDD = +3.3V, TA = +25°C, fRFIN = 315MHz, unless oth- erwise noted.) (Note 1) 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.
