DESCRIPTION:
The IDT54/74FCT374/A/C, IDT54/74FCT534/A/C and
IDT54/74FCT574/A/C are 8-bit registers built using an ad-
vanced 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
)
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-to-
HIGH transition of the clock input.
The IDT54/74FCT374/A/C and IDT54/74FCT574/A/ C have
non-inverting outputs with respect to the data at the D inputs.
The IDT54/74FCT534/A/C have inverting outputs.
