DESCRIPTION:

The FCT163245/A/C 16-bit transceivers are 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 are designed to 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.
