IDT54/74FCT162244T/AT/CT/ET
FEATURES:
DESCRIPTION:
• 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 ≤ 1µA (max.)
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• Balanced Output Drivers:
The FCT162244T 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.

outputfalltimes,reducingtheneedforexternalseriesterminatingresistorswhile
still providing very high speed operation for loads of less than 200pF.
– ±24mA(industrial)
– ±16mA(military)
• Reduced system switching noise
• Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V,
TA = 25°C
• Available in the following packages:
– Industrial: SSOP, TSSOP, TVSOP
– 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 + ∆ICC DHNT + ICCD (fCPNCP/2 + fiNi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current caused by an Input Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
NCP = Number of Clock Inputs at fCP
fi = Input Frequency
Ni = Number of Inputs at fi
