components
The FCT163543/A/C 16-bit latched transceivers are built
using advanced dual metal CMOS technology. These highspeed, low-power devices are organized as two independent 8bit 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-toHIGH 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.
The FCT163543/A/C have series current limiting resistors.
These offer low ground bounce, minimal undershoot, and
controlled output fall times–reducing the need for external
series terminating resistors.

2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.
4. Propagation Delays and Enable/Disable times are with VCC = 3.3V ±0.3V, Normal Range. For VCC = 2.7V to 3.6V, Extended Range, all Propagation Delays
and Enable/Disable times should be degraded by 20%.
