FAST CMOS

16-BIT REGISTERED

TRANSCEIVER

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.
