12-BIT TRI-PORT
BUS EXCHANGER
DESCRIPTION:
The FCT16260T Tri-Port Bus Exchangers are high-speed 12-bit
latched bus multiplexers/transceivers for use in high-speed microprocessor
applications. These Bus Exchangers support memory interleaving with
latched outputs on the B ports and address multiplexing with latched inputs
on the B ports.
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 latch
enable (LE1B, LE2B, LEA1B and LEA2B) inputs control data storage.
When a latch-enable input is high, the latch is transparent. When a latch-
enable input is low, the data at the input is latched and remains latched until
the latch enable input is returned high. Independent output enables (
OE1B
and
OE2B) allow reading from one port while writing to the other port.
The FCT16260T is ideally suited for driving high capacitance loads and
low impedance backplanes. The output buffers are designed with power
off disable capability to allow "live insertion" of boards when used as
backplane drivers.
