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: 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. * * * * 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 - Military: CERPACK FUNCTIONAL BLOCK DIAGRAM 1OE 3OE 1A1 1Y1 1A2 1Y2 1A3 1A4 3A1 3Y1 3A2 3Y2 1Y3 3A3 3Y3 1Y4 3A4 3Y4 2OE 4OE 2A1 2Y1 2A2 2Y2 2A3 2Y3 2A4 2Y4 4A1 4Y1 4A2 4Y2 4A3 4Y3 4A4 4Y4 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
