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 ŽACT11534 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 ŽACT11534 is functionally equivalent to the ŽACT11373 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 nor drive the bus lines significantly. The 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 operations 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 54ACT11534 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT11534 is characterized for operation from -40°C to 85°C.
