description
These 8-bit latches feature three-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 are transparent D-type latches.
While the enable (C) is high the Q outputs will
follow the complements of data (D) inputs. When
the enable is taken low the output will be latched
at the inverses of the levels that were set up at the
D inputs.
A buffered output-control input can be used to
place the eight outputs in either a normal logic
state
(high
or
low
high-impedance state. In the high-impedance
state the outputs neither load nor drive the bus
lines significantly. The high-impedance state and
increased high-logic level provide the capability to
drive the bus lines in a bus-organized system
without need for interface or pull-up components.

The output control (OC) does not affect the
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.

over the full military temperature range of –55

operation from 0
