INDUSTRIAL TEMPERATURE RANGE
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 (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 FCT162374T has balanced output drive with current limiting resistors.
This offers low ground bounce, minimal undershoot, and controlled output fall
timesreducing the need for external series terminating resistors.The
FCT162374T are plug-in replacements for the FCT16374T and ABT16374 for
on-board bus interface applications.
