6. AC Test Conditions:
Input Pulse Voltages: 0.3 V CC to 0.7 V CC
Input rise and fall times: ≤ 10 ns
Input and output reference voltages: 0.5 V CC
Output load: current source I OL max /I OH max ; C L = 30 pF
7. This parameter is tested initially and after a design or process change that affects the parameter.
8. t WC is the time from the rising edge of CS after a valid write sequence to the end of the internal write cycle.
9. Devices identified with Date Code before January 2013 are specified for V CC ≥ 2.5 V only
