FEATURES:
DESCRIPTION:
• 0.5 MICRON CMOS Technology
TheFCT162827T20-bitbuffersarebuiltusingadvanceddualmetalCMOS
technology. These20-bitbusdriversprovidehigh-performancebusinterface
buffering for wide data/address paths or buses carrying parity. Two pair of
NAND-ed output enable controls offer maximum control flexibility and are

• 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)
• VCC = 5V ±10%
• Balanced Output Drivers (±24mA)
• Reduced system switching noise
• Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V,
TA = 25°C
• Available in SSOP and TSSOP packages
