DESCRIPTION:

The FCT3574/A 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 (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 O outputs on the LOW-to­HIGH transition of the clock input.
