The FCT3574/A are 8-bit registers built using an advanced dual metal CMOS technology. These registers consist of eight D-type flip-flops with a buffered common clock and buffered 3-state output control. When the output (OE) input is LOW, the eight outputs are enabled. When the OE input is HIGH, the outputs are in the high-impedance state. Input data meeting the set-up and hold time requirements of the D inputs is transferred to the O outputs on the LOW-toHIGH transition of the clock input.
