FAIRCHILD SEMICONDUCTOR  74VHC14MX  非门, VHC系列, 施密特触发, 6输入, 25 mA, 2V至5.5V, SOIC-14

The is an advanced high speed CMOS Hex Schmitt Inverter 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. Pin configuration and function are the same as the VHC04 but the inputs have hysteresis between the positive-going and negative-going input thresholds, which are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals, thus providing greater noise margin than conventional inverters. An input protection circuit ensures that 0V 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.
