FEATURES:
- - - - - - - - - - 0.5 MICRON CMOS Technology High-speed, low-power CMOS replacement for ABT functions Typical tSK(o) (Output Skew) 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) 25 mil pitch SSOP, 19.6 mil pitch TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch CERPACK packages Extended commercial range of -40°C to +85°C 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 = 25° C
DESCRIPTION:
The FCT16244T/AT/CT/ET 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 16bit operation. These parts are plug in replacements for 54/74ABT16244 where higher speed, lower noise or lower power dissipation levels are desired. The FCT16244T/AT/CT/ET 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.
