Notes:
9. R1=1667Ω and R2=1538Ω for IOH/IOL= –4/8mA, R1=521Ω and R2=481Ω for IOH/IOL= –2/2mA.
10. Unless otherwise noted, test conditions assume signal transition time of 2.5ns or less, timing reference levels of 1.25V, input pulse levels of 0 to 2.5V, and
output loading of the specified IOL/IOH and load capacitance. Shown in (a) and (b) of AC test loads.
11. tCHZ, tCLZ, tEOHZ, and tEOLZ are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ± 200 mV from steady-state voltage.
12. At any given voltage and temperature, tCHZ (max) is less than tCLZ (min).
13. This parameter is sampled and not 100% tested.
