DESCRIPTION:
The FCT163373/A/C 16-bit transparent D-type latches are
built using advanced dual metal CMOS technology. These
high-speed, low-power latches are ideal for temporary stor-
age 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 inputs of FCT163373/A/C can be driven from either
3.3V or 5V devices. This feature allows the use of these
transparent latches as translators in a mixed 3.3V/5V supply
system. With xLE inputs HIGH, the FCT163373/A/C can be
used as buffers to connect 5V components to a 3.3V bus.
