产品概述
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.
