© 2001 Fairchild Semiconductor Corporation DS500454 www.fairchildsemi.com February 2001 Revised February 2001 74LCX27 Low Voltage Triple 3-Input NOR Gate with 5V Tolerant Inputs General Description The LCX27 contains three 3-input NOR gates. The inputs tolerate voltages up to 7V allowing the interface of 5V sys- tems to 3V systems. The 74LCX27 is fabricated with advanced CMOS technol- ogy to achieve high speed operation while maintaining CMOS low power dissipation. Features s 5V tolerant inputs s 2.3V–3.6V VCC specifications provided s 4.9 ns tPD max (VCC = 3.3V), 10 µA ICC max s Power down high impedance inputs and outputs s ±24 mA output drive (V CC = 3.0V) s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s ESD performance: Human body model > 2000V Machine model > 200V Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
