description/ordering information
The
’AC564
devices
are
octal
D-type
edge-triggered flip-flops that feature inverting
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 inverse 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.
OE does not affect internal operations of the flip-flops. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
