These 8-bit latches feature 3-state outputs designed specificallyfor driving highly capacitive or relatively low-impedance loads. Theyare particularly suitable for implementing buffer registers, I/Oports, bidirectional bus drivers, and working registers.
The eight latches of the ´AC11533 are transparent D-typelatches. While the enable (C) is high, the Q\ outputs will follow thecomplements of the (D) inputs. When the output control
A buffered output-control
input can be used to place the eight outputs in either a normal logicstate (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 thecapability to drive the bus lines in a bus-organized system withoutneed for interface or pull-up components.
The output control
doesnot affect the internal operations of the latches. Old data can beretained or new data can be entered while the outputs are off.
The 54AC11533 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. The 74AC11533is characterized for operation from - 40°C to 85°C.
