components
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 (xOE) overrides
the direction control and disables both ports. All inputs are
designed with hysteresis for improved noise margin.

NOTES:

1. See test circuit and waveforms.
2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.
4. Propagation Delays and Enable/Disable times are with VCC = 3.3V ±0.3V, Normal Range. For VCC = 2.7V to 3.6V, Extended Range, all Propagation Delays
and Enable/Disable times should be degraded by 20%.
5. This parameter is guaranteed but not tested.
