74VHC21FT(BJ)

74VHC21FT(BJ) is a CMOS digital silicon monolithic IC. It is an advanced high-speed CMOS dual 4-input AND gate fabricated with silicon gate C²MOS 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 4 stages including a buffer output, which provides high noise immunity and stable output. An input protection circuit ensures that 0 to 5.5V 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 back-up. This circuit prevents device destruction due to mismatched supply and input voltages.
