Slew Rate Derating Values
(Note: 31; notes appear on pages 50-53) ( VDDQ = +2.5V ±0.2V, VDD = +2.5V ±0.2V )
NOTES:
1. All voltages referenced to VSS.
2. Tests for AC timing, IDD, and electrical AC and DC characteristics may be conducted at nominal
reference/supply voltage levels, but the related specifications and device operation are guaranteed for the
full voltage range specified.
3. Outputs measured with equivalent load:
4. AC timing and IDD tests may use a VIL-to-VIH swing of up to 1.5V in the test environment, but input
timing is still referenced to VREF (or to the crossing point for CK/CK), and parameter specifications
are guaranteed for the specified AC input levels under normal use conditions. The minimum slew rate
for the input signals used to test the device is 1V/ns in the range between VIL(AC) and VIH(AC).
