Absolute Maximum Ratings
Operating temperature range ........................................................................................ 0 to + 70 °C
Storage temperature range.................................................................................... – 55 to + 150 °C
Input/output voltage .......................................................................... – 0.5 to min (V_CC + 0.5, 4.6) V
Power supply voltage V_DD / V_DDQ ............................................................................. – 1.0 to + 4.6 V

Notes
1. All voltages are referenced to V_SS.
2. V_IH may overshoot to V_CC + 2.0 V for pulse width of < 4 ns with 3.3 V. V_IL may undershoot to
–2.0 V for pulse width < 4.0 ns with 3.3 V. Pulse width measured at 50% points with amplitude
measured peak to DC reference.
