74LCX02
Low Voltage Quad 2-Input NOR Gate
with 5V Tolerant Inputs
General Description
The LCX02 contains four 2-input NOR gates. The inputs
tolerate voltages up to 7V allowing the interface of 5V sys-
tems to 3V systems.
Features
■ 5V tolerant inputs
■ 2.3V–3.6V VCC specification provided
■ 5.2 ns tPD max (VCC = 3.3V), 10 µA ICC max
The 74LCX02 is fabricated with advanced CMOS technol-
ogy to achieve high speed operation while maintaining
CMOS low power dissipation.
■ Power down high impedance inputs and outputs
■ ±24 mA output drive (VCC = 3.0V)
■ Implements patented noise/EMI reduction circuitry
■ Latch-up performance exceeds 500 mA
■ ESD performance:
Human body model > 2000V
Machine model > 200V

Note 1: The Absolute Maximum Ratings are those beyond which the safety of the device cannot be guaranteed. The device should not be operating at these
limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The “Recommended
Operating Conditions” table will define the conditions for actual device operation.
Note 2: I Absolute Maximum Rating must be observed.
