74VHC14 Hex Schmitt Inverter October 1995 74VHC14 Hex Schmitt Inverter 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 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 back up This circuit prevents device destruction due to mismatched supply and input voltages Features Y Y Y Y Y Y Low power dissipation ICC e 2 mA (Max) at TA e 25 C High noise immunity VNIH e VNIL e 28% VCC (Min) All inputs are equipped with a power down protection function Balanced propagation delays TPLH j TPHL Low
