MC74VHC02
Quad 2−Input NOR Gate
The MC74VHC02 is an advanced high speed CMOS 2−input NOR
gate fabricated with silicon gate CMOS technology. It achieves high
speed operation similar to equivalent Bipolar Schottky TTL while
maintaining CMOS low power dissipation.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V
systems to 3.0 V systems.
Features
• High Speed: t_PD = 3.6 ns (Typ) at V_CC = 5.0 V
• Low Power Dissipation: I_CC = 2 mA (Max) at T_A = 25°C
• High Noise Immunity: V_NIH = V_NIL = 28% V_CC
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Designed for 2.0 V to 5.5 V Operating Range
• Low Noise: V_OLP = 0.8 V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance:
Human Body Model > 2000 V;
Machine Model > 200 V
• Chip Complexity: 40 FETs or 10 Equivalent Gates
• Pb−Free Packages are Available*
