The FCT374T/FCT2374T, FCT534T and FCT574T/ FCT2574T are 8-bit registers built using an advanced dual metal CMOS technology. These registers consist of eight Dtype flip-flops with a buffered common clock and buffered 3state 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. Input data meeting the set-up and hold time requirements of the D inputs is transferred to the Q outputs on the LOW-toHIGH transition of the clock input. The FCT2374T and FCT2574T have balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot and controlled output fall times-reducing the need for external series terminating resistors. FCT2xxxT parts are plug-in replacements for FCTxxxT parts.
