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 ′BCT573 are transparent  
D-type latches. While the latch-enable (LE) input  
ishigh, theQoutputswillfollowthedata(D)inputs.  
When the latch enable is taken low, the Q outputs  
will be latched at the logic levels that were 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) 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 SN54BCT573 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74BCT573 is characterized for operation from 0°C to 70°C.
