DESCRIPTION:
The FCT162952AT/BT/CT/ET 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 (x
CEAB)
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. x
OEAB performs the output enable
function on the B port. Data flow from the B port to A port is similar but requires
using x
CEBA, xCLKBA, and xOEBA inputs. Full 16-bit operation is
achieved by tying the control pins of the independent transceivers together.
The FCT162952AT/BT/CT/ET have balanced output drive with cur-
rent limiting resistors. This offers low ground bounce, minimal undershoot,
and controlled output fall times–reducing the need for external series
terminating resistors. The FCT162952AT/BT/CT/ET are plug-in replace-
ments for the FCT16952AT/BT/CT/ET and ABT16952 for on-board bus
interface applications.
