These octal transparent D-type latches feature  
3-state outputs designed specifically for driving  
highly capacitive or relatively low-impedance  
loads. The ’HCT573 devices are particularly  
suitable for implementing buffer registers, I/O  
ports, bidirectional bus drivers, and working  
registers.

While the latch-enable (LE) input is high, the  
Q outputs respond to the data (D) inputs. When  
LE is low, the outputs are latched to retain the data  
that was 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-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 interface or pullup components.
