NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. All device terminals except FCT162XXX Output and I/O terminals.
3. Output and I/O terminals terminals for FCT162XXX.

The FCT162260T 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 FCT162260T has balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall times reducing the need for external series terminating resistors.
