Note:
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent
damage of the device. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
Recommended Operation and Characteristics :
T
A = 0 to 70 °C; VSS = 0 V; VDD,VDDQ = 3.3 V ± 0.3 V
Notes:
1. All voltages are referenced to VSS.
2. Vih may overshoot to Vdd + 2.0 V for pulse width of < 4ns with 3.3V. Vil may undershoot to
-2.0 V for pulse width < 4.0 ns with 3.3V. Pulse width measured at 50% points with amplitude measured peak
to DC reference.
