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 communi-
cation 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 (x
OE
) overrides
the direction control and disables both ports. All inputs are
designed with hysteresis for improved noise margin.
