description/ordering information
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.
