AC characteristics (except high Z) are tested using the Thevenin load shown in Figure 3 (a). High Z characteristics are tested for all speeds using the test load shown inFigure 3 (c). 6. Test conditions assume signal transition time of 2.6 ns or less, timing reference levels of 1.3 V, input pulse levels of 0 to 2.6 V. 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. 8. tHZOE, tHZBE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (c) of Figure 3. Transition is measured 500 mV from steady-state voltage. 9. This parameter is guaranteed by design and is not tested. [+] Feedback |
