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.
