74VHC14
Hex Schmitt Inverter
General Description
The VHC14 is an advanced high speed CMOS Hex
Schmitt Inverter fabricated with silicon gate CMOS technol-
ogy. It achieves the high speed operation similar to equiva-
lent 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 out-
put signals, thus providing greater noise margin than con-
ventional inverters.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery back up. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
