Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for device operation.
Note 2: Typical values are given for VCC = 5.0V and TA = +25˚C.
Note 3: Current into device pins is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to ground unless otherwise speci-
fied (except VOD and ∆VOD).
Note 4: ESD Rating: HBM (1.5 kΩ, 100 pF)
PLL V CC ≥ 1000V
All other pins ≥ 2000V
EIAJ (0Ω, 200 pF) ≥ 150V
