description

These eight 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 ´ACT11533 are transparent D-typelatches. While the enable (C) is high, the Q\ outputs will follow thecomplements of the (D) inputs. When the output control is taken low, the Q\ outputs willbe latched. The ´ACT11533 is functionally equivalent to the´ACT11373 except for having inverted outputs.

A buffered output-control input can be 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 neitherload nor drive the bus lines significantly. The high-impedance thirdstate and increased drive provide the capability to drive the buslines in a bus-organized system without need for interface or pullupcomponents.

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 54ACT11533 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. The74ACT11533 is characterized for operation from - 40°C to85°C.
