1. General description
The 74HC7014 is a hex buffer with precision Schmitt-trigger inputs. The precisely defined trigger
levels are lying in a window between 0.55 × VCC and 0.65 × VCC. It makes the circuit suitable
to operate in a highly noisy environment. Input shorts are allowed to -1.5 V and +16 V without
disturbing other channels. Inputs include clamp diodes. This enables the use of current limiting
resistors to interface inputs to voltages in excess of VCC. Schmitt trigger inputs transform slowly
changing input signals into sharply defined jitter-free output signals.
