description  
These 8-bit latches feature 3-state outputs  
designed specifically for driving highly capacitive  
or relatively low-impedance loads. The devices  
are particularly suitable for implementing buffer  
registers, I/O ports, bidirectional bus drivers, and  
working registers.

The eight latches are D-type transparent latches.  
When the latch-enable (LE) input is high, the Q  
outputs follow the data (D) inputs. When LE is  
taken low, the Q outputs are latched at the logic  
levels set up at the D Inputs.

A buffered output-enable (OE) input can be used  
to place the eight outputs in either a normal logic  
state (high or low logic levels) or the high-imped-  
ance state. In the high-impedance state, the  
outputs neither load nor drive the bus lines  
significantly. The high-impedance state and  
increased drive provide the capability to drive bus  
lines in a bus-organized system without need for  
interface or pullup components.

OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered  
while the outputs are in the high-impedance state.  
The SN54AC573 is characterized for operation over the full military temperature range of –55 C to 125 C.  
The SN74AC573 is characterized for operation from –40 C to 85 C.
