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 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.

FEATURES:

? Common features:

– 0.5 MICRON CMOS Technology

– High-speed, low-power CMOS replacement for ABT functions
