Notes:
4. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified
IOL/IOH and 30-pF load capacitance.
5. This part has a voltage regulator which steps down the voltage from 5V to 3.3V internally. tpower time has to be provided initially before a read/write operation is
started.
6. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ±500 mV from steady-state voltage.
7. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device.
