FAST CMOS 16-BIT
BUFFER/LINE DRIVER
DESCRIPTION:
The FCT166244T 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 ABT16244 where
higher speed, lower noise or lower power dissipation levels are desired.
The FCT166244T is 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.
