6V at VCC = 5V,TA = 25°C 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.
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 all...
