AC & DC Operating Conditions

Recommended DC Operating Conditions

Notes:

1. Under all conditions, VDDQ must be less than or equal to VDD.

2. VDDQ tracks with VDD. AC parameters are measured with VDD and VDDQ tied together.

AC & DC Input Measurement Levels

AC and DC Logic Input Levels for Single-Ended Signals

AC and DC Input Levels for Single-Ended Command and Address Signals

Notes:

1. For input only pins except RESET

, Vref = VrefCA (DC).

2. Refer to “Overshoot and Undershoot Specifications” on page 30.

3. The ac peak noise on V

Ref

may not allow V

Ref

to deviate from V

RefCA(DC)

by more than +/-1% VDD (for

reference: approx. +/- 15 mV).

4. For reference: approx. VDD/2 +/- 15 mV.
