• RE: SN74AHC1G08: What is the schmitt trigger action?

  

  Clemens Ladisch

  1. All modern logic families have a little bit of hysteresis at the inputs, but it's only 100 mV or so. Its only purpose is to work around the inductance of the pins and the bond wires, so there is no hysteresis that is guaranteed to be available for…
