The FCT162245T 16-bit transceiver is built using advanced dual metal
CMOS technology. These high-speed, low-power transceivers are ideal
for synchronous communication between two busses (A and B). The
Direction and Output Enable controls operate these devices as either two
independent 8-bit transceivers or one 16-bit transceiver. The direction
control pin (xDIR) controls the direction of data flow. The output enable pin
(xOE) overrides the direction control and disables both ports. All inputs are
designed with hysteresis for improved noise margin.
The FCT162245T has balanced output drive with current limiting
resistors. This offers low ground bounce, minimal undershoot, and
controlled output fall times– reducing the need for external series terminating
resistors. The FCT162245T are plug-in replacements for the FCT16245T
and ABT16245 for on-board interface applications.
