ABSOLUTE MAXIMUM RATINGS

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 - VEE) = 2.375V to 3.8V, outputs loaded with 50

Ω ±1% to VCC - 2V; CLK_SEL, FSEL_ = high or low; MR = low; |VID| = 0.095V to

the lower of (VCC - VEE ) and 3V. Typical values are at (VCC - VEE) = 3.3V, VIHD = VCC - 1V, VILD = VCC - 1.5V.) (Notes 1–4)
