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

2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V). All other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ΔICC DHNT + ICCD (fCPNCP/2 + fiNi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
