16-Bit Transparent Latch

The FCT16373T 16-bit transparent D-type latch is 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 is ideally suited for driving high-capacitance loads and lowimpedance backplanes. The output buffers are designed with power off disable capability to allow "live insertion" of boards when used as backplane drivers.
