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.
