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.
