74AHC1G17; 74AHCT1G17

Single Schmitt trigger buffer

The 74AHC1G17 and 74AHCT1G17 are single buffers 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 to 5.5 V
  • Overvoltage tolerant inputs to 5.5 V
  • High noise immunity
  • CMOS low power dissipation
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
  • Symmetrical output impedance
  • Balanced propagation delays
  • Input levels:
    • For 74AHC1G17: CMOS level
    • For 74AHCT1G17: TTL level
  • SOT353-1 and SOT753 package options
  • ESD protection:
    • HBM JESD22-A114E: exceeds 2000 V
    • MM JESD22-A115-A: exceeds 200 V
    • CDM JESD22-C101C: exceeds 1000 V
  • Specified from -40 °C to +125 °C


  • Wave and pulse shapers
  • Astable multivibrators
  • Monostable multivibrators
