DESCRIPTION:
bidirectional,12-bit, registered, bus multiplexers for use in synchronous memory
interleaving applications. All registers have a common clock and use a clock
enable (CExxx) on each data register to control data sequencing. The output
enables and mux select (OEA, OEB and SEL) are also under synchronous
control allowing direction changes to be edge triggered events.
between the A port and either/both of the B ports. The clock enable (CE1B,
CE2B, CEA1B and CEA2B) inputs control the data storage. Both B ports have
a common output enable (OEB) to aid in synchronously loading the B registers
from the B port.
This offers low ground bounce, minimal undershoot, and controlled output fall
times-reducing the need for external series terminating resistors.
whenever the input goes to high impedance. This prevents "floating" inputs and
eliminates the need for pull-up/down resistors.

The FCT162H272T synchronous tri-port bus exchangers are high-speed,
The tri-port bus exchanger has three 12-bit ports. Data may be transferred
The FCT162H272T has balanced output drive with current limiting resistors.
The FCT162H272T has "Bus Hold" which retains the input's last state
