Switch shown in Logic '1' Input Position. Logic '0' < 1.0V _ Logic '1' > 4.5V _ NOTE: All devices contain diodes to protect inputs against damage due to high static voltages or electric fields; however, it is advised that precautions be taken not to exceed the maximum recommended input voltages. All unused inputs must be connected to an appropriate logic level (VDD or GND).
