Quad. 2-input NOR Gates
ADE-205-061B(Z)
Rev.2
September 1995
Description
The HD74LVC02 has four 2-input NOR gates in a 14 pin package. Low voltage and high speed operation
is suitable at the battery drive product (note type personal computer) and low power consumption extends
the life of a battery for long time operation.
Features
• VCC = 2.0 V to 5.5 V
• All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
• Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
• Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)
• High output current ±24 mA (@VCC = 3.0 V to 5.5 V)
