The 74AHCT1G14 is a single 1-input Schmitt-trigger inverter gate with a standard push-pull output. The device is designed for operation with a power supply range of 4.5V to 5.5V. The gate performs the positive Boolean function: Y = A


  • Supply Voltage Range from 4.5V to 5.5V
  • ± 8 mA Output Drive at 5.0V
  • CMOS low power consumption
  • Schmitt Trigger Action at All Inputs Make the Circuit Tolerant for Slower Input Rise and Fall Time
  • ESD Protection per JESD 22 - Exceeds 200-V Machine Model (A115-A) - Exceeds 2000-V Human Body Model (A114-A) - Exceeds 1000-V Charged Device Model (C101C)
  • Latch-Up Exceeds 100mA per JESD 78, Class II
  • SOT25 and SOT353: Assemb°C with “Green” Molding Compound (no Br, Sb)
  • Lead Free Finish / RoHS Compliant


  • General Purpose Logic
