description/ordering information
The
’ACT564
devices
are
octal
D-type
edge-triggered flip-flops that feature 3-state
outputs designed specifically for driving highly
capacitive or relatively low-impedance loads.
They are particularly suitable for implementing
buffer registers, I/O ports, bidirectional bus
drivers, and working registers.
On the positive transition of the clock (CLK) input,
the Q outputs are set to the complements of the
logic levels set up at the data (D) inputs.
A buffered output-enable (OE) input places the
eight outputs in either a normal logic state (high or
low logic levels) or the high-impedance state. In
the high-impedance state, the outputs neither
load nor drive the bus lines significantly. The
high-impedance
state
and
increased
drive
provide the capability to drive bus lines without
interface or pullup components.
