FEATURES:
DESCRIPTION:
The FCT163373 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 inputs of FCT163373 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 can be used as a buffer to connect 5V components to a 3.3V bus.
