description/ordering information
These 8-bit flip-flops feature 3-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. The devices
are particularly suitable for implementing buffer
registers, I/O ports, bidirectional bus drivers, and
working registers.
The eight flip-flops of the
′AC574 devices are
D-type edge-triggered flip-flops. On the positive
transition of the clock (CLK) input, the Q outputs
are set to the logic levels set up at the data (D)
inputs.
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
the increased drive provide the capability to drive
bus lines in a bus-organized system without need
for interface or pullup components.
OE does not affect internal operations of the
flip-flop. Old data can be retained or new data can
be entered while the outputs are in the
high-impedance state.
