Description of the high and low trigger,friends do not understand Take a look at:

High level trigger is a trigger voltage between the signal input and ground can be understood as a way of the signal input terminal and VCC cathode short trigger;

Low trigger means is the voltage between the signal input terminal and the ground for the OV trigger mode can be understood as a way of the signal input terminal and GND negative short trigger
