Pin Descriptions
Truth Table(Note 1)
H
= HIGH Voltage Level
X
= Immaterial
L
= LOW Voltage Level
= LOW-to-HIGH Transition.
Note 1: The data output functions may be enabled or disabled by various signals at the OE and DIR 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 appropriate clock inputs. Also applies to data I/O (A and B: 8-15) and #2 control
pins.
