description
These octal transparent D-type 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, the Q
outputs follow the data (D) inputs. When LE 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) 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 the increased drive
provide the capability to drive bus lines without
interface or pullup components.
OE does not affect internal operations of the
latches. Old data can be retained or new data can
be entered while the outputs are off.
