Triple 3-Input NOR Gate
The 74VHC27 is an advanced high speed CMOS 3-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 0V to 7V CAN be applied to the input pins without regard to the supply voltage. This device CAN be used to Interface 5V to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages.
