Function Label Instruction
Signal Input 1+ The first signal input anode
1- The first signal input cathode
2+ The second signal input anode
2- The second signal input cathode
3+ The third signal input anode
3- The third signal input cathode
4+ The fourth signal input anode
4- The fourth signal input cathode
Power Input VCC DC power anode(*)
GND DC power supply cathode
Signal Output O1 The first signal output
O2 The second signal output
O3 The third signal output
O4 The fourth signal output(*):The DC power supply is the same as the signal output voltage. For example, if the signal is from 3.3V to 5V, then VCC=5V input.
