1 GND = 0 V, VCCP, VCCQL = 1.8 V ±5%, TJ = –40×C to +95×C, CL = 50 pF
All other VCC = 3.3 V ± 5%, TJ = –40×C to +95×C, CL = 50 pF
2 Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond
the maximum rating may affect device reliability or cause permanent damage to the device.

Natural Convection, Junction-to-ambient thermal resistance1,2
1 Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board
thermal resistance.
