FAST CMOS 16-BIT

REGISTER (3-STATE)

DESCRIPTION:

The FCT162374T 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 (x

OE)andclock(xCLK)controlsareorganizedto

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 FCT162374T has balanced output drive with current limiting resistors.

This offers low ground bounce, minimal undershoot, and controlled output fall

times–reducing the need for external series terminating resistors.The

FCT162374T are plug-in replacements for the FCT16374T and ABT16374 for

on-board bus interface applications.
