DESCRIPTION:
metal CMOS technology. These high-speed, low-power devices are organized
as two independent 8-bit D-type latched transceivers with separate input and
output control to permit independent control of data flow in either direction. For
example, the A-to-B Enable (xCEAB) must be low in order to enter data from
the A port or to output data from the B port. xLEAB controls the latch function.
When xLEAB is low, the latches are transparent. A subsequent low-to-high
transition of xLEAB signal puts the A latches in the storage mode. xOEAB
performs output enable function on the B port. Data flow from the B port to the
A port is similar but requires using xCEBA, xLEBA, and xOEBA inputs. Flow-
through organization of signal pins simplifies layout. All inputs are designed with
hysteresis for improved noise margin.
This offers low ground bounce, minimal undershoot, and controlled output fall
times–reducing the need for external series terminating resistors. The
FCT162543T is a plug-in replacement for the FCT16543T and 54/74ABT16543
for on-board bus interface applications.

The FCT162543T has balanced output drive with current limiting resistors.
