DESCRIPTION:

The FCT16374T 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 simplifies layout. All

inputs are designed with hysteresis for improved noise margin.

The FCT16374T is ideally suited for driving high-capacitance loads and

low-impedance backplanes. The output buffers are designed with power off

disable capability to allow "live insertion" of boards when used as backplane

drivers.
