Description

AI
Each circuit functions as a NAND gate or inverter, but because of the Schmitt action, it has different input threshold levels for positive-going (VT+) and for negative-going (VT-) signals. The hysteresis or backlash, which is the difference between the two threshold levels (VT+- VT-), is typically 800 millivolts. These circuits are temperature-compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
