DESCRIPTION:

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

) 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
