74LV02Quad 2-input NOR gate
FEATURES Wide operating voltage: 1.0 to 5.5 V Optimized for low voltage applications: 1.0 to 5.5 V Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V,
Tamb = 25°C Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V,
Tamb = 25°C Output capability: standard ICC category: SSI
DESCRIPTIONThe 74LV02 is a low-voltage Si-gate CMOS device that is pin and
function compatible with 74HC/HCT02.
The 74LV02 provides the 2-input NOR function.
QUICK REFERENCE DATAGND = 0 V; Tamb = 25°C; tr = tf ≤ 2.5 ns
NOTES: CPD is used to determine the dynamic power dissipation (PD in μW)
PD = CPD × VCC2 × fi (CL VCC2 fo) where:
fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
(CL VCC 2 fo) = sum of the outputs. The condition is VI = GND to VCC.

ABSOLUTE MAXIMUM RATINGS1, 2In accordance with the Absolute Maximum Rating System (IEC 134).
Voltages are referenced to GND (ground = 0V).
NOTES: Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
DC ELECTRICAL CHARACTERISTICSOver recommended operating conditions. Voltages are referenced to GND (ground = 0V).

NOTE: All typical values are measured at Tamb = 25°C.
AC CHARACTERISTICSGND = 0V; tr = tf ≤ 2.5ns; CL = 50pF; RL = 1KΩ
NOTES: Unless otherwise stated, all typical values are measured at Tamb = 25°C Typical values are measured at VCC = 3.3 V. Typical values are measured at VCC = 5.0 V.
AC WAVEFORMSVM = 1.5 V at VCC ≥ 2.7 V and ≤ 3.6 V;
VM = 0.5 × VCC at VCC < 2.7 V and ≥ 4.5 V;
VOL and VOH are the typical output voltage drop that occur with the
output load.
