The 16-bit transceivers are built using advanced dual metal
CMOS technology. These high-speed, low-power transceiv-
ers 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 trans-
ceivers or one 16-bit transceiver. The direction control pin
(xDIR) controls the direction of data flow. The output enable
pin (x
OE
) overrides the direction control and disables both
ports. All inputs are designed with hysteresis for improved
noise margin.
The FCT16245T are ideally suited for driving high-capaci-
tance loads and low-impedance backplanes. The output buff-
ers are designed with power off disable capability to allow "live
insertion" of boards when used as backplane drivers.
The FCT162245T have 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.
The FCT166245T are suited for very low noise, point-to-
point driving where there is a single receiver, or a light lumped
