IDT54/74FCT16244T/AT/CT FAST CMOS 16-BIT BUFFER/LINE DRIVER MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS 16-BIT IDT54/74FCT16244T/AT/CT BUFFER/LINE DRIVER FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology The FCT16244T 16-Bit Buffer/Line Driver is for bus interface or signal High-speed, low-power CMOS replacement for ABT functions buffering applications requiring high speed and low power dissipation. These Typical tSK(o) (Output Skew) < 250ps devices have a flow through pin organization, and shrink packaging to simplify Low input and output leakage 1A (max.) board layout. All inputs are designed with hysteresis for improved noise margin. ESD > 2000V per MIL-STD-883, Method 3015 > 200V using The three-state controls allow independent 4-bit, 8-bit or combined 16-bit machine model (C = 200pF, R = 0) operation. These parts are plug in replacements for 54/74ABT16244 where High drive outputs (32mA IOH, 64mA IOL) higher speed, lower noise or lower power dissipation levels are desired. Power off disable outputs permit live insertion The FCT16244T is ideally suited for driving high capacitance loads Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V, (>200pF) and low impedance backplanes. Thesehigh driv buffers are TA = 25C designed with power off disable capability to allowlive insertio of boards when Available in the following packages: used in a backplane interface.
