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 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. Flowthrough 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.
