General Description
The VHC14 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 0 V to 7 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.

Features
• High Speed: tPD = 5.5 ns (Typ.) at VCC = 5 V
• Low Power Dissipation: ICC = 2 μA (Max.) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 28% VCC (Min.)
• Power down protection is provided on all inputs
• Low Noise: VOLP = 0.8 V (Max.)
• Pin and Function Compatible with 74HC14
