The 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/AT/CT/ET are 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.

The FCT162244T/AT/CT/ET have 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.

The FCT166244T/AT/CT are suited for very low noise, point-to-point driving where there is a single receiver, or a very light lumped load (<100pF).  The buffers are designed to limit the output current to levels which will avoid noise and ringing on the signal lines without using external series terminating resistors.
The FCT162H244T/AT/CT/ET have "Bus-Hold" which reains the input's last state whenever the input goes to high impedance.  This prevents "floating" inputs and eliminates the need for pull-up/down resistors.
