DESCRIPTION:
The FCT16374T/AT/CT/ET and FCT162374T/AT/CT/ET
16-bit edge-triggered D-type registers are built using ad-
vanced 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
)
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 sim-
plifies layout. All inputs are designed with hysteresis for
improved noise margin.
The FCT16374T/AT/CT/ET are 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.
The FCT162374T/AT/CT/ET have balanced output drive
with current limiting resistors. This offers low ground bounce,
minimal undershoot, and controlled output fall times– reduc-
ing the need for external series terminating resistors. The
FCT162374T/AT/CT/ET are plug-in replacements for the
FCT16374T/AT/CT/ET and ABT16374 for on-board bus inter-
face applications.
