IDT74FCT166244AT/CT FAST CMOS 16-BIT BUFFER/LINE DRIVER INDUSTRIAL TEMPERATURE RANGE IDT74FCT166244AT/CT FAST CMOS 16-BIT BUFFER/LINE DRIVER DESCRIPTION: FEATURES: The FCT166244T 16-Bit Buffer/Line Driver is for bus interface or signal 0.5 MICRON CMOS Technology buffering applications requiring high speed and low power dissipation. These High-speed, low-power CMOS replacement for ABT functions devices have a flow through pin organization, and shrink packaging to simplify Typical tSK(o) (Output Skew) < 250ps board layout. All inputs are designed with hysteresis for improved noise Low input and output leakage 1A (max.) margin. The three-state controls allow independent 4-bit, 8-bit or combined 16- Light drive balanced output of 8mA bit operation. These parts are plug in replacements for ABT16244 where Minimal system switching noise higher speed, lower noise or lower power dissipation levels are desired. Typical VOLP (Output Ground Bounce) < 0.25V at VCC = 5V, The FCT166244T is suited for very low noise, point-to-point driving TA = 25C where there is a single receiver, or a very light lumped load (<100pF). The Power off disable outputs permit live insertion buffers are designed to limit the output current to levels which will avoid noise Available in SSOP package and ringing on the signal lines without using external series terminating resistors.
