Fig. 15-37 This circuit is essentially a zero-crossing detector with hysteresis. The circuit has a 100-mV hysteresis, which can be used in applications, where very fast transition times are required at the output-even though the input signal is very slow. The hysteresis loop also reduces false triggering because of noise on the input. The waveforms in Fig. 15-37B show the trip points developed by the hysteresis loop. Figures 15-32B and 15-32C show the pin connections, and electrical characteristics, respectively. Harris semiconductor, Linear & Telecom ICs. 1991. p. 4-30.
