74HC14 (Hex Inverting Schmitt Trigger) KA78R33 The device can be clearedIntroduction : 74HC14 is a hex inverter with Schmitt trigger inputs. This device features reducedinput threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, thisenables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitttrigger inputs transform slowly changing input signals into sharply defined jitter free output signals. Features : Supply voltage range: 0. 5V to +7.
