DESCRIPTION:
The FCT163374 16-bit edge-triggered D-type register is 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 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.

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.
