description

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 4+ — VT1-), 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.
