74HC14; 74HCT14 Hex inverting Schmitt trigger Product datasheet, Rev. 1.0 Aug 08, 2024 1.General Description The 74HC14 and 74HCT14 are hex inverter with Schmitt-trigger inputs. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Schmitt 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 V to 6.0 V  High noise immunity  CMOS low power dissipation  Latch-up performance exceeds 250 mA  Unlimited rise and fall times  Complies with JEDEC standards: • JESD8C (2.7 V to 3.6 V) • JESD7A (2.0 V to 6.0 V)  ESD protection:  • HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 3500 V • CDM ANSI/ESDA/JEDEC JS-002 Class C3 exceeds 2000 V Multiple package options Rev. 1.0 – Aug 08, 2024 1 74HC14; 74HCT14 Hex inverting Schmitt trigger 3.Ordering Information Table 1.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Table 4. Absolute Maximum Ratings In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND.
