AC test conditions
Notes
1
For test conditions, see “AC test conditions”, Figures A, B, and C.
2
This parameter is measured with output load condition in Figure C.
3
This parameter is sampled but not 100% tested.
4tHZOE is less than tLZOE, and tHZC is less than tLZC at any given temperature and voltage.
5tCH is measured as high if above VIH, and tCL is measured as low if below VIL.
6
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.
7
Write refers to GWE, BWE, and BW[a:d].
8
Chip select refers to CE0, CE1, and CE2.

Output load: For tLZC, tLZOE, tHZOE, tHZC, see Figure C. For all others, see Figure B.
Input pulse level: GND to 2.5V. See Figure A.
Input rise and fall time (measured at 0.25V and 2.25V): 2 ns. See Figure A.
Input and output timing reference levels: 1.25V.
