This 10-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.
10ĆBIT BUSĆINTERFACE FLIPĆFLOP
WITH 3ĆSTATE OUTPUTS
SCBS089B − FEBRUARY 1989 − REVISED NOVEMBER 1993
DW OR NT PACKAGE
The ten flip-flops are edge-triggered D-type flip-flops. On the positive transition of the clock, the Q outputs will
be complementary to the data (D) inputs.
A buffered output-enable (OE) input can be used to place the ten 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 SN74BCT29822 is characterized for operation from 0°C to 70°C.
