components
DESCRIPTION:
The FCT163374/A/C 16-bit edge-triggered D-type regis-
ters are built using advanced dual metal CMOS technology.
These high-speed, low-power registers are ideal for use as
buffer registers for data synchronization and storage. The
Output Enable (x
OE
) and clock (xCLK) controls are organized
to operate each device as two 8-bit registers or one 16-bit
register with common clock. Flow-through organization of
signal pins facilitates ease of layout. All inputs are designed
with hysteresis for improved noise margin.
The inputs of FCT163374/A/C can be driven from either
3.3V or 5V devices. This feature allows the use of these
devices as translators in a mixed 3.3V/5V supply system.

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.
