Maximum Ratings[5]

Input Voltage Relative to VSS:...............................VSS – 0.3V

Input Voltage Relative to VDDQ or AVDD: ............. VDD + 0.3V

Storage Temperature: ................................ –65 C to + 150 C

Operating Temperature:.................................... 0 C to +70 C

Maximum ESD............................................................. 2000V

Maximum Power Supply: ................................................ 5.5V

This device contains circuitry to protect the inputs against

damage due to high static voltages or electric field. However,

precautions should be take to avoid application of any voltage

higher than the maximum rated voltages to this circuit. For

proper operation, VIN and VOUT should be constrained to the

range.

VSS < (VIN or VOUT)< VDD

Unused inputs must always be tied to an appropriate logic

voltage level (either VSS or VDD).

Notes:

5. The voltage on any input or I/O pin canno t exceed th power pin during power-up. Power supply sequencing is NOT required.

6. Applicable to input signals: Sel100/133, Sel(0:1)), Spread#, PWRDN#, Mult(0:1)

7. Although internal pull-up or pull-down resistors have a typical value of 250k, this value may vary between 200k and 500k.

8. All outputs loaded as per Table 4.
