• Output load: For t
• Input pulse level: GND to 3V. See Figure A.
• Input rise and fall time (measured at 0.3V and 2.7V): 2 ns. See Figure A.
• Input and output timing reference levels: 1.5V.
For test conditions, see “AC test conditions”, Figures A, B, and C.
This parameter is measured with output load condition in Figure C.
This parameter is sampled but not 100% tested.

This is a synchronous device. All addresses must meet the specified setup and hold times for all rising edges of CLK. All other synchronous inputs must
meet the setup and hold times for all rising edges of CLK when chip is enabled.
