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 SN74BCT29823 has noninverting 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. Thehigh-impedancestateandincreaseddriveprovidethecapabilitytodrivebuslineswithoutneed  
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 SN74BCT29823 is characterized for operation from 0°C to 70°C.
