The FCT16373T/AT/CT/ET and FCT162373T/AT/CT/ET
16-bit transparent D-type latches are built using advanced
dual metal CMOS technology. These high-speed, low-power
latches are ideal for temporary storage of data. They can be
used for implementing memory address latches, I/O ports,
and bus drivers. The Output Enable and Latch Enable controls
are organized to operate each device as two 8-bit latches, or
one 16-bit latch. Flow-through organization of signal pins
simplifies layout. All inputs are designed with hysteresis for
improved noise margin.
The FCT16373T/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 FCT162373T/AT/CT/ET have 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
FCT162373T/AT/CT/ET are plug-in replacements for the
FCT16373T/AT/CT/ET and ABT16373 for on-board interface
applications.
