FAST CMOS 16-BIT
BUFFER/LINE DRIVER
IDT54/74FCT16244T/AT/CT
FEATURES:
DESCRIPTION:
• 0.5 MICRON CMOS Technology
The FCT16244T 16-Bit Buffer/Line Driver is for bus interface or signal
bufferingapplicationsrequiringhighspeedandlowpowerdissipation. These
deviceshaveaflowthroughpinorganization,andshrinkpackagingtosimplify
boardlayout. Allinputsaredesignedwithhysteresisforimprovednoisemargin.
The three-state controls allow independent 4-bit, 8-bit or combined 16-bit
operation. Thesepartsarepluginreplacementsfor54/74ABT16244where
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
designedwithpoweroffdisablecapabilitytoallow"liveinsertion"ofboardswhen
usedinabackplaneinterface.
• High-speed, low-power CMOS replacement for ABT functions
• Typical tSK(o) (Output Skew) < 250ps
• Low input and output leakage ≤ 1µA (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 = 25°C
• Available in the following packages:
– Industrial: SSOP, TSSOP
– Military:CERPACK
