The FCT163952 16-bit registered transceiver is built using advanced
dual metal CMOS technology. These high-speed, low-power devices are
organized as two independent 8-bit D-type registered transceivers with
separate input and output control for independent control of data flow in either
direction. For example, the A-to-B Enable (xCEAB) must be LOW to enter
data from the A port. xCLKAB controls the clocking function. When xCLKAB
toggles from low-to-high, the data present on the A port will be clocked into
the register. xOEAB performs the output enable function on the B port. Data
flow from the B port to A port is similar but requires using xCEBA, xCLKBA,
and xOEBA inputs. Full 16-bit operation is achieved by tying the control pins
of the independent transceivers together.
The FCT163952 has series current limiting resistors. These offer low
ground bounce, minimal undershoot, and controlled output fall times鈥?/div>
reducing the need for external series terminating resistors.
