These 8-bit latches 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 F573 are transparent  
D-type latches. While the latch enable (LE) input  
is high, the Q outputs follow the data (D) inputs.  
When the latch enable 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 a high-  
impedance 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 without need for interface or pullup  
components.

The output enable (OE) input 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 SN54F573 is characterized for operation over the full military temperature range of 55°C to 125°C. The  
SN74F573 is characterized for operation from 0°C to 70°C.
