IDT74FCT16373AT/CT
INDUSTRIAL TEMPERATURE RANGE
FAST CMOS 16-BIT
TRANSPARENT LATCH
DESCRIPTION:
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 low-
impedance backplanes. The output buffers are designed with power off disable
capability to allow "live insertion" of boards when used as backplane drivers.
