description/ordering information
These octal edge-triggered D-type flip-flops
feature 3-state outputs designed specifically for
bus driving. They are particularly suitable for
implementing
buffer
registers,
I/O
ports,
bidirectional bus drivers, and working registers.
The eight flip-flops enter data on the low-to-high
transition of the clock (CLK) input.
A buffered output-enable (OE) input can be used
to place 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.
