0002F—10/25/02

Notes:

1. CL incluces probe and jig capacitance.

2. IDD tested with clock and data inputs held at VDDQ or GND, and IO = 0 mA.

3. All input pulses are supplied by generators having the following characteristics: PRR @10 MHz,

Zo=50

Ω, input slew rate = 1 V/ns ±20% (unless otherwise specified).

4. The outputs are measured one at a time with one transition per measurement.

5. VTT = VREF = VDDQ/2

6. VIH = VREF + 310mV (AC voltage levels) for differential inputs. VIH = VDDQ for LVCMOS input.

7. VIL = VREF - 310mV (AC voltage levels) for differential inputs. VIL = GND for LVCMOS input.

8. tPLH and tPHL are the same as tpd
