These octal D-type transparent 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.

While the latch-enable (LE) input is high, outputs  
(Q) respond to the data (D) inputs. When LE islow,  
the outputs are latched to retain the data that was  
set up.

A buffered output-enable (OE) input can be used  
to place the eight outputs in either a normal logic  
state (high or low) or a high-impedance state. In  
thehigh-impedancestate, theoutputsneitherload  
nor drive the bus lines significantly. The  
high-impedance state and the increased drive  
provide the capability to drive bus lines without  
interface or pullup components.

OE does not affect internal operation of the  
latches. Old data can be retained or new data can  
be entered while the outputs are in the  
high-impedance state.  
The SN54ALS573C and SN54AS573A are characterized for operation over the full military temperature range  
of 55°C to 125°C. The SN74ALS573C and SN74AS573A are characterized for operation from 0°C to 70°C.
