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 ’HCT373 devices are

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.
