74VHC02M

FAIRCHILD SEMICONDUCTOR  74VHC02M  或非门, VHC系列, 4门, 2输入, 8 mA, 2V至5.5V, SOIC-14

The is an advanced high-speed CMOS quad 2-input NOR Gate fabricated with silicon gate CMOS technology. It achieves the high-speed operation similar to equivalent bipolar schottky TTL while maintaining the CMOS low power dissipation. The internal circuit is composed of 3 stages, including buffer output, which provide high noise immunity and stable output. An input protection circuit insures that 0 to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages.
