1 74hc14 ; 74 HCT14. Hex inverting Schmitt trigger Rev. 7 19 November 2015 Product data sheet 1. General description The 74hc14 ; 74 HCT14 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 VCC. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals. 2. Features and benefits Complies with JEDEC standard no. 7A. Low-power dissipation 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. Applications Wave and pulse shapers Astable multivibrators Monostable multivibrators Nexperia 74hc14 ; 74 HCT14.
