‡ 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 conditions 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 latches 54ACT11533 feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The eight latches of the 54ACT11533 are transparent D-type latches. While the enable (C) is high, the Q outputs will follow the complements of the (D) inputs. When the output control OC is taken low, the Q outputs will be latched. The 54ACT11533 is functionally equivalent to the 4ACT11373 except for having inverted outputs.

A buffered output-control (OC) input of 54ACT11533 can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a highimpedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance third state and increased drive of 54ACT11533 provide the capability to drive the bu s lines in a bus-organized system without need for interface or pullup components.

The output control (OC) of 54ACT11533 does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are off.

The 54ACT11533 is characterized for operation over the full military temperature range of 55°C to 125°C. The 74ACT11533 is characterized for operation from 40°C to 85°C.
