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 Bi-
polar 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 volt-
age 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
