Maximum ratings are the extreme limits to which the GL651USB can be exposed without permanently
damaging it. The GL651USB contains circuitry to protect the inputs against damage from high static
voltages; however, do not apply voltages higher than those shown in the table. Keep V
IN
and V
OUT
within
the range GND
(V

. Connect unused inputs to the appropriate voltage level, either GND
or V
