The FCT16244T 16-Bit Buffer/Line Driver is for bus interface or signal
buffering applications requiring high speed and low power dissipation. These
devices have a flow through pin organization, and shrink packaging to simplify
board layout. All inputs are designed with hysteresis for improved noise margin.
The three-state controls allow independent 4-bit, 8-bit or combined 16-bit
operation. These parts are plug in replacements for 54/74ABT16244 where
higher speed, lower noise or lower power dissipation levels are desired.
The FCT16244T is ideally suited for driving high capacitance loads
(>200pF) and low impedance backplanes. These "high drive" buffers are
designed with power off disable capability to allow "live insertion" of boards when
used in a backplane interface.
