‡ Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated  onditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output current ratings are observed

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 74ACT11534 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 74ACT11534 is functionally equivalent to the 4ACT11373 except for having inverted outputs.

An output-control input (OC) of the 74ACT11534 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 74ACT11534 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
