BUS EXCHANGER
DESCRIPTION:
The FCT162H272T synchronous tri-port bus exchangers are high-speed,
bidirectional,12-bit,registered,busmultiplexersforuseinsynchronousmemory
interleaving applications. All registers have a common clock and use a clock
enable (
CExxx)oneachdataregistertocontroldatasequencing. Theoutput
enables and mux select (
OEA, OEB and SEL) are also under synchronous
control allowing direction changes to be edge triggered events.
The tri-port bus exchanger has three 12-bit ports. Data may be transferred
between the A port and either/both of the B ports. The clock enable (
CE1B,
CE2B,CEA1BandCEA2B)inputscontrolthedatastorage. BothBportshave
a common output enable (
OEB)toaidinsynchronouslyloadingtheBregisters
from the B port.

This offers low ground bounce, minimal undershoot, and controlled output fall
times-reducing the need for external series terminating resistors.
The FCT162H272T has "Bus Hold" which retains the input's last state
whenevertheinputgoestohighimpedance. Thisprevents"floating"inputsand
eliminates the need for pull-up/down resistors.
