BUFFER/LINE DRIVER
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:
– ±24mA(industrial)
– ±16mA(military)
• Reduced system switching noise
• Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V,
TA = 25°C
The FCT162244T 16-Bit Buffer/Line Driver is for bus interface or signal

The three-state controls allow independent 4-bit, 8-bit or combined 16-bit
operation. Thesepartsarepluginreplacementsfor54/74ABT16244where
