- Latch-up performance exceeds 250mA per JESD 17.  
- ESD protection exceeds JESD 22 (2000-V Human-Body Model).  

This device is commonly used in signal conditioning, noise filtering, and waveform shaping applications.

Application Scenarios & Design Considerations

Single Schmitt-Trigger Inverter Gate 5-SC70 -40 to 125

Alternative Part Number

  • 74AHCT1G14GW,125 --: Single Schmitt-trigger inverter in the AHCT family with the same logic function and 5V-tolerant TTL-compatible inputs, available in a small SC-88/SOT-363 package; a direct functional replacement from a different vendor.
  • MC74VHCT1G14DFT1G --: Single Schmitt-trigger inverter with TTL-compatible inputs and similar 5V operating range, offered in a compact SOT-353 package; a well-established cross-vendor alternative with comparable drive and speed.
  • SN74LVC1G14DBVR --: Single Schmitt-trigger inverter from TI's LVC family in SOT-23-5; it provides the same inverting Schmitt function and wide supply range, though input thresholds differ slightly from AHCT, so verify logic-level compatibility.
