Notes:
7. At any given temperature and voltage condition, tHZCE is less than tLZCE and tHZWE is less than tLZWE
.
8. Output loading is specified with CL=5 pF as in AC Test Loads. Transition is measured ±500mV from steady state voltage.
9. Capacitance derating applies to capacitance different from the load capacitance shown in AC Test Loads.
10. tRC = Read Cycle Time.
