AC Test Conditions
Input Pulse Levels ................................................... 0V to 3V
Input Rise and Fall Times (10% - 90%) ....................... <5 ns
Input and Output Timing Reference Levels ....................1.5V
Notes
8. WE must be HIGH during SRAM read cycles.
9. Device is continuously selected with CE and OE both LOW.
10.Measured ±200 mV from steady state output voltage.
11. If WE is LOW when CE goes LOW, the outputs remain in the high impedance state.
