DESCRIPTION:

•
•
The FCT374T 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.
