Product Description:
Electrical parameters:
High-level triggering refers to a triggering method where there is a voltage between the signal input terminal and the ground. It can be understood as a triggering method where the signal input terminal is short-circuited to the VCC positive pole;
Low-level triggering refers to a triggering method in which the voltage between the signal input terminal and the ground is OV. It can be understood as a triggering method in which the signal input terminal is short-circuited with the negative pole of GND.
