±0.3V,
Normal Range or
V
CC
= 2.7V to 3.6V, Extended Range

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-to-
HIGH transition of the clock input.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS 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 ex-
tended periods may affect reliability.
