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 34.
3. The ac peak noise on VRef may not allow VRef to deviate from VRefCA(DC) by more than +/-1% VDD (for
reference: approx. +/- 15 mV).
4. For reference: approx. VDD/2 +/- 15 mV.
