DESCRIPTION

This 8-bit latch features 3-state outputs designed specifically for driving highly capacitive or relatively lowimpedance

loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers,

and working registers.

The eight latches of the SN54HC373-DIE 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.
