† Electrical Characteristics are over Recommended Operating Conditions unless otherwise stated.
‡ Typical figures are at 25×C with nominal +5V supply and are for design aid only
Note 1: All of the above test conditions use a test source impedance which matches the device’s impedance.
Note 2: dBm is referenced to 600Ω unless otherwise stated.
