Notes:
8. Resistor values for V
= 5V are: R1 = 1179
and R2 = 868
. Resistor values for V
= 3.3V are R1 = 317
and R2 = 348
.
9. Unless otherwise noted, 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 I
/I
and load capacitance. Shown in (a) and (b) of AC Test Loads.
10.Do not use the burst mode, if device operates at a frequency above 50 MHz.
11. t
, t
, and t
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.
12.At any given voltage and temperature, t
WEOZ
min. is less than t
