Functional Description
The FCT373T and FCT573T consist of eight latches with
three-state outputs for bus organized applications. When latch
enable (LE) is HIGH, the flip-flops appear transparent to the
data. Data that meets the required set-up times are latched
when LE transitions from HIGH to LOW. Data appears on the
bus when the (OE) is LOW. When output enable is HIGH, the
bus output is in the impedance state. In this mode, data may
be entered into the latches. The FCT573T is identical to the
FCT373T except for the flow-through pinout, which simplifies
board design.
The outputs are designed with a power-off disable feature to
allow for live insertion of boards.
