FUNCTIONAL BLOCK DIAGRAM

IDT54/74FCT574/A/C

DESCRIPTION:

The FCT574 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) 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 FCT574 has non-inverting outputs with respect to the data at the D
inputs.

NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability. No terminal voltage may exceed
Vcc by +0.5V unless otherwise noted.
