74LVC02A
Low-Voltage CMOS Quad
2-Input NOR Gate
With 5 V−Tolerant Inputs
The 74LVC02A is a high performance, quad 2−input NOR gate
operating from a 1.2 to 3.6 V supply. High impedance TTL compatible
inputs significantly reduce current loading to input drivers while TTL
compatible outputs offer improved switching noise performance. A VI
specification of 5.5 V allows 74LVC02A inputs to be safely driven
from 5 V devices.
Current drive capability is 24 mA at the outputs.
Features
• Designed for 1.2 V to 3.6 V VCC Operation
• 5 V Tolerant Inputs − Interface Capability With 5 V TTL Logic
• 24 mA Output Sink and Source Capability
• Near Zero Static Supply Current (10 mA) Substantially Reduces
System Power Requirements
• ESD Performance: Human Body Model >2000 V;
Machine Model >200 V
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
4. Typical values are measured at TA = 25°C and VCC = 3.3 V, unless stated otherwise.
5. tpd is the same as tPLH and tPHL.
6. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGH−to−LOW (tOSHL) or LOW−to−HIGH (tOSLH); parameter
guaranteed by design.

VCC = 2.3 V to 2.7 V
VCC = 3.0 V to 3.6 V
8. CPD is used to determine the dynamic power dissipation (PD in mW).
PD = CPD x VCC2 x fi x N + S (CL x VCC2 x fo) where:
fi = input frequency in MHz; fo = output frequency in MHz
CL = output load capacitance in pF VCC = supply voltage in Volts
N = number of outputs switching
S(CL x VCC2 x fo) = sum of the outputs.
