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