NOTES:
1.Formula only for dc to 2 MHz.
2.Input clocks with duty cycles other than 50% affect bus performance. Timing parameters affected by input clock
duty cycle are identified by (a) and (b). To recalculate the approximate bus timing values, substitute the following
expressions in place of 1/8 t
cyc
in the above formulas, where applicable:
(a) (1-DC) x 1/4 t
cyc
(b) DC x 1/4 t
cyc
Where:
DC is the decimal value of duty cycle percentage (high time).
3.All timing is shown with respect to 20% V
DD
and 70% V

, unless otherwise noted.
