This 8-bit latch features 3-state outputs designed specifically
for driving highly-capacitive or relatively low-impedance loads. It
is particularly suitable for implementing buffer registers, I/O
ports, bidirectional bus drivers, and working registers.
The eight latches of the 74ACT11373 are transparent D-type
latches. While the latch-enable (LE) input is high, the Q outputs
follow the data (D) inputs. When the enable is taken low, the Q
outputs are latched at the levels that were set up at the D inputs.
A buffered output-enable
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-impendance third state and increased
drive provide the capability to drive the bus lines in a
bus-organized system without need for interface or pullup components.

the internal operations of the latches. Old data can be retained or
new data can be entered while the outputs are off.
The 74ACT11373 is characterized for operation from -40°C to
