DESCRIPTION:
The FCT163952A/B/C 16-bit registered transceivers are
built using advanced dual metal CMOS technology. These
high-speed, low-power devices are organized as two indepen-
dent 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 x
OEBA
inputs. Full 16-bit operation is
achieved by tying the control pins of the independent trans-
ceivers together.
The FCT163952A/B/C have series current limiting resis-
tors. These offer low ground bounce, minimal undershoot, and
controlled output fall times鈥搑educing the need for external
series terminating resistors.
