DESCRIPTION:
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.
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.
This offers low ground bounce, minimal undershoot, and controlled output fall
times – reducing the need for external series terminating resistors.
The FCT162260T Tri-Port Bus Exchangers are high-speed 12-bit latched
The Tri-Port Bus Exchanger has three 12-bit ports. Data may be transferred
The FCT162260T has balanced output drive with current limiting resistors.
