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.
