Shutdown control Turns the output off with a LOW (0V to
0.5V) or short-circuit.
Output on/off control Possible logic selections:
Turn the output on using a LOW (0V to
0.5V) or short-circuit, turn the output off
using a HIGH (4.5V to 5V) or open-circuit.
Turn the output on using a HIGH (4.5V to
5V) or open-circuit, turn the output off
using a LOW (0V to 0.5V) or short-circuit.
