DESCRIPTION:
The FCT16260AT/CT/ET and the FCT162260AT/CT/ET
Tri-Port Bus Exchangers are high-speed 12-bit latched bus
multiplexers/transceivers for use in high-speed microproces-
sor 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 FCT16260AT/CT/ET are 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.
The FCT162260AT/CT/ET have balanced output drive
with current limiting resistors. This offers low ground bounce,
minimal undershoot, and controlled output fall times - reduc-
ing the need for external series terminating resistors.
