V
CC
= 3.3V ±0.3V, Normal Range or V
CC
= 2.7V to 3.6V, Extended
Range
CMOS power levels (0.4µ W typ. static)
Rail-to-Rail output swing for increased noise margin
Low Ground Bounce (0.3V typ.)
Inputs (except I/O) can be driven by 3.3V or 5V components
Available in SSOP, TSSOP and TVSOP Packages
DESCRIPTION:
The FCT163374/A/C 16-bit edge-triggered D-type registers 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 (xOE) 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
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
