description  
These eight flip-flops feature 3-state outputs  
designed for implementing buffer registers, I/O  
ports, bidirectional bus drivers, and working  
registers.

The eight flip-flops of the AC11534 are edge-  
triggered, D-type flip-flops. On the positive  
transition of the clock, the Q outputs are set to the  
complement of the logic levels at the D inputs. The  
AC11534 is functionally equivalent to the  
AC11374 except for having inverted outputs.

An output-control input (OC) is used to place the  
eight outputs in either a normal logic state (high or  
low logic levels) or a high-impedance state. In the  
high-impedance state, the outputs neither load  
NC – No internal connection  
nor drive the bus lines significantly.  
The  
FUNCTION TABLE  
(each filp-flop)  
high-impedance third state and increased drive  
provide the capability to drive the bus lines in a  
bus-organized system without need for interface  
or pull-up components. The output control (OC)  
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.
