description
This 9-bit bus-interface flip-flop features 3-state
outputs designed specifically for driving highly
capacitive or relatively low-impedance loads. It is
particularly suitable for implementing wider buffer
registers, I/O ports, bidirectional bus drivers with
parity, and working registers.
The nine flip-flops are edge-triggered D-type flip-flops. With the clock-enable (CLKEN) input low, the flip-flops
store data on the low-to-high transitions of the clock. Taking CLKEN high disables the clock buffer, thus latching
the outputs. The SN74BCT29824 has inverting data (D) inputs. Taking the clear (CLR) input low causes the nine
Q outputs to go low independent of the clock.
A buffered output-enable (OE) input can be used to place the nine outputs in either a normal logic state (high
or low) or a 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 need
for interface or pullup components.
The output enable (OE) does not affect the internal operation of the flip-flops. Old data can be retained or new
data can be entered while the outputs are in the high-impedance state.
The SN74BCT29824 is characterized for operation from 0
°
C to 70
°
C.
