DESCRIPTION:
The FCT2374T is an 8-bit register 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 has 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.
FCT2374T parts are plug-in replacements for FCT374T parts.
