DESCRIPTION
The FCT374T/FCT2374T, FCT534T and FCT574T/
FCT2574T 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 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-to-
HIGH 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.
