DESCRIPTION:
The IDT54/74FCT374/A/C, IDT54/74FCT534/A/C and IDT54/74FCT574/A/C 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 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-toHIGH 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.
