The 54FCT574T is an 8-bit register consists 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 54FCT574T operates at -55C to +125C.
