7414: Hex Schmitt Triggers (Inverting)
All six Schmitt triggers may be used independently. On any single trigger, a low input produces a high output. A high input produces a low output.
Unlike a normal TTL gate, the inputs possess a snap action used to condition slowly changing or noisy inputs. The input impedance of this circuit is about 6K. The trip point for a positive-going signal is 1.7 volts. The trip point for a negative-going signal is 0.9 volt. The snap action or hysteresis range is 0.8 volt.
