DESCRIPTION:
The FCT16952T 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 FCT16952T is ideally suited for driving high-capacitance loads and
low-impedance backplanes. The output buffers are designed with power off
disable capability allowing "live insertion" of boards when used as backplane
drivers.
