IDT54/74FCT16244T/AT/CT FAST CMOS 16-BIT BUFFER/LINE DRIVER MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS 16-BIT BUFFER/LINE DRIVER IDT54/74FCT16244T/AT/CT FEATURES: * * * * * * * * * 0.5 MICRON CMOS Technology High-speed, low-power CMOS replacement for ABT functions Typical tSK(o) (Output Skew) < 250ps Low input and output leakage 1A (max.) ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) High drive outputs (-32mA IOH, 64mA IOL) Power off disable outputs permit "live insertion" Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V, TA = 25C Available in the following packages: - Industrial: SSOP, TSSOP, TVSOP - Military: CERPACK DESCRIPTION: 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.
