TRANSPARENT
LATCH
DESCRIPTION:
The FCT162373T 16-bit transparent D-type latch is built using advanced
dual metal CMOS technology. This high-speed, low-power latch is ideal for
temporary storage of data. It 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 FCT162373T has balanced output drive with current limiting resistors.
This offers low ground bounce, minimal undershoot, and controlled output fall
times–reducing the need for external series terminating resistors. The
FCT162373T is a plug-in replacement for the FCT16373T and ABT16373 for
on-board interface applications.
