Does the 4069 inverter have more hysteresis than a Schmitt trigger?
I'm thinking about building a ring tester for inductors, in particular a TV flyback transformer. There's a nicely documented schematic here that uses a 4069 hex inverter IC to make an oscillator and perform other functions. (That schematic is an updated version of the original.)
I happen to have a pile of MC14584B hex Schmitt triggers and I think I can use one to replace the inverter 4069 in that schematic. Is there any reason to think it won't work?
I understand the hysteresis provided by a Schmitt trigger but the 4069 datasheet is confusing me: The "on" and "off" voltages seem farther apart than for the Schmitt trigger. Does the 4069 really have more hysteresis than the Schmitt trigger? I'm guessing I'm not reading the datasheet correctly.
