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 xOE 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.
