74AHC14; 74AHCT14

Hex inverting Schmitt trigger

The 74AHC14; 74AHCT14 is a hex inverter with Schmitt-trigger inputs. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

Features and benefits

  • Wide supply voltage range from 2.0 V to 5.5 V
  • Overvoltage tolerant inputs to 5.5 V
  • High noise immunity
  • CMOS low power dissipation
  • Balanced propagation delays
  • Input levels:
    • For 74AHC14: CMOS level
    • For 74AHCT14: TTL level
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
    • CDM JESD22-C101C exceeds 1000 V
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
  • Multiple package options
  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
