8 Detailed Description
8.1 Overview
The SNx414 and SNx4LS14 Schmitt-Trigger devices contain six independent inverters. They perform the Boolean function Y = A in positive logic.
Schmitt-Trigger inputs are designed to provide a minimum separation between positive and negative switching thresholds. This allows for noisy or slow inputs that would cause problems such as oscillation or excessive current draw with normal CMOS inputs.

8.3 Feature Description
The device can operate from very slow transition edge inputs. This device has high noise immunity.
8.4 Device Functional Modes
Table 1 lists the functional modes of the SNx414 and SNx4LS14.
