Note 8: Typical figures are at T

= 25˚C, and represent most likely parametric norms.

Note 9: Test limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). Performance is guaranteed only at V

REF

= 1.4V and a clock duty cycle

of 50%. The limits for V

REF

and clock duty cycle specify the range over which reasonable performance is expected. Tests are performed and limits guaranteed with

clock low and high levels of 0.3V and V

−0.3V, respectively.

Note 10: I

is the current consumed by the switching of the output drivers and is primarily determined by the load capacitance on the output pins, the supply

voltage, V

, and the rate at which the outputs are switching (which is signal dependent). I

+...+C

) where V

is the output driver

power supply voltage, C

is the total capacitance on the output pin, and f

is the average frequency at which that pin is toggling.
