The FCT162244T 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 FCT162244T has balanced output current levels and current limiting
resistors. These offer low ground bounce, minimal undershoot, and controlled
output fall times, reducing the need for external series terminating resistors while
still providing very high speed operation for loads of less than 200pF.
