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/Oports,andbusdrivers.TheOutputEnableandLatchEnablecontrols

are organized to operate each device as two 8-bit latches, or one 16-bit latch.

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.
