DESCRIPTION:
The FCT162952T 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 FCT162952T have balanced output drive with current limiting resistors.
This offers low ground bounce, minimal undershoot, and controlled output fall
times鈥搑educing the need for external series terminating resistors. The
FCT162952T is a plug-in replacement for the FCT16952T and ABT16952 for
on-board bus interface applications.
