The 74FCT574T is an 8-bit register consisting of eight D-type flip-flops with a buffered common clock and buffered 3-state output control. When the output enable (OE) input is low, the eight outputs are enabled. When the OE input is high, the outputs are in the high-impedance state. The 74FCT574T operates at -40C to +85C.
