74HC14 74HCT14 Hex inverting Schmitt trigger Rev. 9 13 August 2021 Product data sheet 1. General description The 74HC14 74HCT14 is a hex inverter with Schmitt-trigger inputs. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of V . Schmitt CC trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals. 2. Features and benefits Wide supply voltage range from 2.0 to 6.0 V CMOS low power dissipation High noise immunity Unlimited input rise and fall times Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Complies with JEDEC standards: JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0 V) ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from -40 C to +85 C and from -40 C to +125 C 3.
