description
The ’FCT374T devices are high-speed, low-power, octal D-type flip-flops, featuring separate D-type inputs for
each flip-flop. These devices have 3-state outputs for bus-oriented applications. A buffered clock (CP) and
output-enable (OE) inputs are common to all flip-flops. The eight flip-flops in the ’FCT374T store the state of
their individual D inputs that meet the setup-time and hold-time requirements on the low-to-high CP transition.
When OE is low, the contents of the eight flip-flops are available at the outputs. When OE is high, the outputs
are in the high-impedance state. The state of OE does not affect the state of the flip-flops.
These devices are fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the
outputs, preventing damaging current backflow through the device when it is powered down.
