NOTES:
1. H = HIGH Voltage Level
L = LOW Voltage Level
X = Don’t Care
↑ = LOW-to-HIGH Transition
2. The data output functions may be enabled or disabled by various signals at the x
OE or xDIR inputs. Data input functions are always enabled, i.e.
data at the bus pins will be stored on every LOW-to-HIGH transition of the clock inputs.
