description/ordering information
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 ’HC373 devices are transparent D-type
latches. 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 levels that were set up at the D inputs
